Describe how g(x) = 4f(x) transforms the graph of the parent function f(x) = x2.

The graph of the parent function is stretched by 4 units.

Step-by-step explanation:

Multiplication of a function by a positive scalar:

When we multiply a function by a positive scalar a, the graph of the function is stretched by a units.

In this question:

g(x) is function f(x) multiplied by 4, which means that the graph of the parent function is stretched by 4 units.
