Let f(x)= 3x+2, g(x)= -4x, and h(x)= x²-4 compute the following.

f(x) + g(x)

g(f(0))

In the picture above.

Step-by-step explanation:

I hope that it's a clear solution.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
