    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.
