Question

What is the range of the function f(x) = √x - 8 + 6?

O f(x) ≥-8
Of(x) ≥-6
O f(x) ≥ 6
O f(x) ≥ 8

Answer 1

answer is f(x) ≥ 6

Explanation:

original function was y=√x

then y=√x-8 which means shifting graph to a new vertex (8,0)

then we will have y=√x-8 + 6 which will shift the graph to the new vertex (8,6)

that means that the new range will be from 6 to positive infinity
