Question

If you horizontally stretch the quadratic parent function, f(x) = X^2 by a factor

of 5, what is the equation of the new function?

Answer:

g(x) = x^2/25

Explanation:

For a horizontal stretch by a factor of k, x is replaced by x/k.

g(x) = f(x/5) = (x/5)^2 = x^2/25

The new function is ...

g(x) = x^2/25
