Question

Answer if you can :)
If f(x) = -7x – 3 and g(x) = radical over x+6,
what is (fºg)(-2)

Answer 1

-17

Explanation:

Plug in -2 as your x value for the g(x) equation and simplify.

`g(-2)=√(-2+6) \\g(-2)=√(4) \\g(-2)=2`

Next, plug in your g(x) value (2) to the f(x) equation for x and simplify.

`f(2)=-7(2)-3\\f(2)=-14-3\\f(2)=-17`
