Question

given that (-2,-8) is on the graph of f(x), find the corresponding point for the function f (x) -1

Answer 1

Answer:

(- 2, - 9 )

Step-by-step explanation:

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

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Then f(x) - 1 is f(x) shifted down 1 unit

Then

(- 2, - 8 ) → (- 2, - 8 - 1 ) → (- 2, - 9 ) ← corresponding point
