The Math Forum: Ask Dr. Math: Determining if a Function Is Even or Odd

Out of the swimming pool and into the math classroom! Young mathematicians analyze two linear functions representing the number of liters of water in a pool as it drains over time. They must evaluate functions, interpret function...

A few more examples can't hurt. An informative video continues the examination of even and odd functions from a prior video. It looks at two additional examples of functions, one that is even and one that is neither even nor odd.

Here's a hint: look at the exponents. Scholars watch a video that shows two examples of how to algebraically prove whether a function is even or odd. They then see how the exponents in a polynomial function relate to the determination.

Going up? Wait, it might be going down! Learners watch a video to see how to use the derivative and critical points to find where a function is either increasing or decreasing. Individuals use the rate of change to solve real-world...

Despite what you thought, you can differentiate between continuity and differentiability. Using a short lesson, pupils learn how differentiability and continuity relate to each other. It provides three descriptions of when a function is...

Is it possible to tell if a table of values represents a linear function or a nonlinear function? One way is to graph the ordered pairs to see if it makes a straight line. But, take a look at the rate of change in the table. If the rate...

Learners who view this video should gain a better understanding of the difference between a geometric sequence and an arithmetic sequence. The video includes an example of each, with step-by-step instructions on how to figure out which...

How does the vertical line test help you decide if the graph of an equation is a function? The instructor draws a graph and then draws the line of the equation. She demonstrates how to use the vertical line test to determine if the graph...

A student asks Dr. Math how to evaluate a composite function. Dr. Math gives a systematic way to evaluate composite functions. Be sure to read the second response as well to findout how to evaluate functions of several compositions and...
