Question

If f(x) = 2x - 3 and g(x) = Radical over x-8, what is (fºg)(24)?

Answer 1

Answer:

5

Step-by-step explanation:

Plug in 24 for x in your g(x) equation.

$g(24)=\sqrt{24-8} \\g(24)=\sqrt{16} \\g(24)=4$

Next, plug in your g(x) value, 4, to your f(x) equation for x.

$f(4)=2(4)-3\\f(4)=8-3\\f(4)=5$
