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

Jlenok [28]

Answer:

6

Step-by-step explanation:

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

$g(4)=\sqrt{4-3} \\g(4)=\sqrt{1} \\g(4)=1$

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

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