Question

Suppose f(x) = x2 and g(x) = 5x2. Which statement best compares the graph

of g(x) with the graph of f(x)?

Answer 1

the graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

Explanation:

Answer 2

The transformation is

`g(x)=5f(x)`

Whenever you transform a function like

`f(x)\mapsto kf(x)`

You're stretching the function vertically. So, the graph of g(x) is the graph of f(x), stretched vertically with a scale factor of 5.
