Reading Graphs

How do letters and numbers create a picture? Scholars learn to create input/output tables to graph functions. They graph both linear and nonlinear functions by creating tables and plotting points. 

Practice graphing basic equations. Algebra learners complete a table showing values of x and y. They graph the results on a coordinate grid. There are six problems: three equations are linear, and three are quadratic. The "show your...

Watch as your knowledge of quadratic functions grows parabolically. An educational video shows scholars how to graph quadratic functions. The method shown here is to create a table of values and graph the function by hand.

After correcting the last problem in his previous video, Sal explains how to graph quadratic functions. Those with difficulty graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at...

It's a straight line to understanding how to graph linear functions. Scholars watch an informative video to learn the process of graphing linear functions. They understand how to make and fill in a table of values and then plot the...

Graphing functions by hand is pretty easy. A comprehensive video reviews how to graph different function types. It looks at the constant, identity, quadratic, cubic, absolute value, square root, cube root, reciprocal, and squared...

There are rabbits, rabbits, rabbits everywhere. Not this group of rabbits. Use a table to find some x and y values to create a graph to solve this word problem. It's a rather peculiar word problem in that it is trying to find when a...

Box and whiskers have more to do with data than they do with cats! A video lesson describes how to plot, analyze, and compare box plots. Mathematicians first learn to create a box plot and then how to use information about the quartiles...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

Profit from this interactive on graphing and interpreting functions. An interactive allows learners to plot a square root function representing a company's profits. They answer some challenge questions that require interpreting this...
