Question

If f(x) = 2x - 2 and g(x) = x}, what is (gºf)(4)?

Answer 1

We conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Explanation:

Given

`f(x) = 2x - 2`

`g(x) = x`

We have to determine (gºf)(4).

(gºf)(4) = g(f(4))

f(4) = 2(4)-2

= 8 - 2

= 6

Thus,

(gºf)(4) = g(f(4)) = g(6) = 6

Therefore, we conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6
