If you horizontally stretch the quadratic parent function, Rx) = x2, by a factor
of 3, what is the equation of the new function?

Answer 1

Rx)=1/3x^2

Explanation:

A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.

In the graph, the red line is the parent function and the blue line is the horizontally stretched function. See how the blue line appears to be stretched (horizontally).
