Suppose f(x)=x^2 and g(x)=(1/5x)^2. which statement best compares the graph of g(x) with the graph of f(x)?

g(x) is the image of f(x) after stretched horizontally

by scale factor = 5

Step-by-step explanation:

∵ f(x) = x² ⇒ quadratic function

∵ g(x) = (1/5 x)² ⇒ The image of f(x) after one transformation

* Stretches or compresses horizontally:

  It means stretches away from the y-axis

  or compresses toward the y-axis

* If f(x) = (ax)²  :

∵ |a| > 1 is a compression by factor of 1/a

∵ 0 < |a| < 1 is a stretch by factor of 1/a

∵ x-coordinate of f(x) multiplied by 1/5

∵ 0 < 1/5 < 1

∴ The transformation is ⇒ stretched horizontally

∴ g(x) is the image of f(x) after stretched horizontally

  by scale factor = 1 ÷ 1/5 = 5
