Question

Given that (0,3) is on the graph of f(x), find the corresponding point for the function f(x)-2

Answer 1

(0 , 1)

Explanation:

given y = f(x), then

y = f(x) + c is a vertical translation

• If c > 0 then vertical shift up of a units

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

here c = - 2, hence shift down of f(x) by 2 units

(0, 3) → (0, 3 - 2 ) = (0, 1)
