Answer 1

i got for F(4) :24
and G(-3) : -81

Answer 2

You need f(4). Take the function f. Where you see x, replace x with 4. Then evaluate it.

\(f(\color{red}{x}) = -5\color{red}{x} + 4\)

To find f(4), we replace x with 4:

\(f(\color{red}{4}) = -5\color{red}{\times4} + 4\)

\(f(4) = -20 + 4\)

\(f(4) = -16\)

Answer 3

Now try the same thing for function g.
Write out function g in full.
Then replace x with -3.
Then evaluate the right side.

Answer 4

Unfortunately, @yese30 's answers above are both incorrect.
