Consider the functions ​g(x)=2x+1 and ​h(x)=2x+2 for the domain 0 a. Without evaluating or graphing the​ functions, how do the ranges​ compare?
b. Graph the two​ functions, and describe each range over the given interval.

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)
