Question

This is a tough one :/
If f(x) = -x + 7 and g(x) = radical of x– 3,
what is (f º g)(4)

Answer 1

6

Explanation:

To solve, first plug in 4 as your x value for your g(x) equation.

`g(4)=√(4-3) \\g(4)=√(1) \\g(4)=1`

Next, plug in the value of g(4) into your f(x) equation for x.

`f(1)=-1+7\\f(1)=6`
