Answer:

Not possible

Step-by-step explanation:

The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).

g(-2) = √x - 16 = √-2 - 16

This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.
