If an object and its image under the transformation shear(or stretch) are given, how can we find the invariant line.

A point on the ocean rises and falls as wave pass Suppose that a wave passes every 4 s, and the height of each wave from the crest to the trough in 0.5 m. a) how do we graph the height of the point relative to tis average height for a complete cycle, starting at the crest of a wave. And how do...

How are the graphs of y=x^2-3x and y=3x-x^2 related? I know that 3x-x^2 is a reflection of y=x^2-3x but what else do they have income besides that and their intersection points? Same with the graphs of y=f(x) and x=f(y), how are they related? Thank you.

Wow! These things are boogers! :eek: any way to make these things easier?

Helping my grandson with math. Some new (to me) terms. Quatratics: What is the "Mapping Rule" What are transformations?
