Question

What is the effect on the graph of f(x) = x² when it is transformed to

h(x) = 5x² + 10?

A. The graph of f(x) is vertically stretched by a factor of 5 and shifted 10 units up.

B. The graph of f(x) is horizontally compressed by a factor of 5 and
shifted 10 units to the left.

C. The graph of f(x) is horizontally stretched by a factor of 5 and
shifted 10 units up.

D. The graph of f(x) is vertically stretched by a factor of 5 and shifted 10 units to the left.

Answer 1

The answer would be A. Basically think of the stretching as multiplication. And the + or - after x refers to the y axis

Answer 2

A

Explanation:

The '5' stretches it vertically by factor of 5 and the '10' shifts it UP 10 units
