Question

Given that (-3,5) is on the graph of f(x), find the corresponding point for the function f(x) - 4.

Answer 1

(- 3, 1 )

Explanation:

Given f(x) then f(x) + c represents a vertical translation of f(x)

• if c > 0 then shift up by c units

• if c < 0 then shift down by c units

Thus for f(x) - 4

(- 3, 5 ) → (- 3, 5 - 4 ) → (- 3, 1 )
