Question

Write a function g whose graph represents the indicated transformation of the graph f.

3. f(x)= x-4; translation 2 units to the left and a vertical stretch by a factor of 2

Answer 1

g(x) = 2x - 4

Explanation:

Translating 2 units to the left gives

`(x+2)-4=x-2`

Stretching vertically by a factor of 2,

`g(x)=2(x-2)=2x-4`
