Can somebody please help me?

Second option,domain:  negative infinity, 4 and range, negative infinity, 3

The domain are all the x's that you can input into a function. It looks like the function goes to all x's from negative infinity until it hits positive 4. that's why it is -infinity, 4 for the domain.

The range is all the y's that are outputted. As you can see, the function goes to all y's from negative infinity to 3.

Step-by-step explanation:

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)
