Question

The function f(x)=2x is transformed to g(x) = 8x - 2.

Describe the transformation(s) that occurred.

Answer 1

Vertical stretch of 4

Vertical translation of 2 units down

Explanation:

Since f(x)=2x is the base function, g(x) = 8x - 2 shows an "a" value which has been multiplied by 4 and a "c" value which shows a vertical translation of -2.
