Calculate
F(16) and g(3)

f(16) = 3.    f(3) = 16.

Step-by-step explanation:

So, the only thing we have to do, is plug the functions into its variables.

1. f(16) = - 1

2. f(16) = 4 - 1 (since 4 x 4 will give 16, we will break 16 to 4)

3. f(16) = 3. (subtract and get the answer)

g(x)

G(3) = + 7

g(3) = 9 + 7

g(3) = 16. (There we go, we got the answer!)

Hope this helps, and have a wonderful day!
