In this shorts video we will answer a standardized math test questions about a function: true or false. We will use the vertical line test to examine each of the four graphs. We will understand that the vertical line test is when you...

In this video, the teacher explains how to use the vertical line test to determine if a graph is a function or not. The viewer is presented with four graphs and asked to identify which one is not a function. The teacher demonstrates...

In this math lesson, we learn about translating linear functions through horizontal and vertical transformations. The teacher explains the concept of function notation and how it relates to these transformations, providing examples and...

In this math video, the teacher explains the concept of functions and demonstrates how to determine if a graph is a function using the vertical line test. The teacher also shows how to identify a non-function in a table of values by...

👉 Learn about every thing you need to know to understand the domain and range of functions. We will look at functions represented as equations, tables, mapping, and ordered pairs. The domain is the set of all possible x or input values...

After a friend of mine got a tattoo with a representation of the cosecant function, it got me thinking about how there's another sense in which this function is a tattoo on math, so to speak.

In his essay “The Unreasonable Effectiveness of Mathematics”, the physicist Eugine Wigner said that “the enormous usefulness of mathematics in the natural sciences is something bordering on the mysterious”. This statement was inspired by...

In this short math video we will be comparing linear, exponential & quadratic functions. We will be asked to correctly complete two statements about the three graphed functions on a coordinate plane. We will first be asked which of the...

In this math video we are learning about functions, the slope, y--intercept & equation from a table. This is a four part constructed response question where we are presented with a table of values representing a linear function. In Part...

In this math video we will learn facts about linear functions. We will discuss the characteristics of a linear function in slope-intercept form. We will review that slope-intercept form is y=mx+b. We will discover that m represents the...

In this math video we will find the first four terms of an arithmetic sequence using function notation. We will be given the equation in function notation representing an arithmetic sequence and asked to evaluate the function for values...

New ReviewIn this math video lesson, students analyze a graph with six plotted points and determine which point could be removed so the relation becomes a function. The exemplar solution models how to apply the vertical line test, showing that...

In this shorts math video we will review how to write an exponential function to answer a standardized math test question. We will identify the key information provided in the problem - initial amount, rate of increase or decrease, and...

In this Algebra 1 lesson, we will identify the correct vertex form of the given graph of a quadratic function. We dive into Common Core Standard HS.F-BF.3 as we explore how transformations affect functions — specifically...

In this math video we will compare functions to answer an open response question from a standardized test. We will be asked to interpret a real world function. We will write an equation to represent the relationship between x and y of...

In this short math video we will be comparing linear functions using unit rates & one time fees to answer a standardized math test question. We will consider two different bills with costs incurred for hourly rate (unit rate or slope)...

In this Algebra 1 video, students quickly analyze a table of values and four possible functions to determine which function best represents the data. We begin by noticing the domain increases by 1 each time, but the range does not have a...

In this short math video we will use function notation to translate a function. We will understand that translating a function down impacts the y-coordinate of EVERY point on the function. We will rewrite the function by subtracting 4...

In this video lesson we will learn how to evaluate functions using function notation , as well as, how to interpret function notation. We will learn that function notation is a way to name functions to help us differentiate one function...

This video explains how to determine if a relation is a function using mapping diagrams, tables, and the vertical line test. The lesson covers the concepts of inputs and outputs, ordered pairs, and the definition of a function as a...

In this step-by-step Algebra 1 walkthrough, we model and solve a real-world quadratic function problem involving an object launched upward from a platform!
<
br/>
We
’re told:
-The object starts 10 meters...

In this video lesson we will review the effects of constants, h, a, and k on a linear function. We will learn that the constant h effects by transforming a function horizontally left or right. We will learn that the constant a will...

In this video lesson we will learn how to reflect a linear function. We will also learn how to identify a reflection using a graph and how to represent a linear reflection using function notation. We will discover that a linear...
