Question

If you horizontally stretch the quadratic parent function, f(x) = x2, by a factor of 5, what is the equation of the new function?

a.g(x) = (5x)2
b.g(x) = x2
c.g(x) = 5x2
d.g(x) = (x)2

Answer 1

g(x)=(1/5x)^2

Hope this helps you :)

Answer 2

None of the above .

A horizontal stretch is given by (1/5)x^2

5x^2 gives a vertical stretch factor 5
