The function graphed with a solid line is the parent function, y=f(x) . Which of the following describes the transformed function, y=4f(x), which is shown with a dotted line?

Question

Responses

The parent function has been vertically stretched by a factor of 4.

The parent function has been vertically stretched by a factor of 1/4

The parent function has been vertically compressed by a factor of 4.

The parent function has been vertically compressed by a factor of 1/4

Answer 1

The transformed function \( y = 4f(x) \) indicates that the parent function \( y = f(x) \) has been vertically stretched by a factor of 4.

Therefore, the correct response is:

The parent function has been vertically stretched by a factor of 4.
