If the degree of a polynomial function is even and the leading coefficient is negative, then the end behavior of the function is
O f(x)
→ as x + +
O f(x) + -o as x + +
O f(x)
→ -- as X - - and f(x)
oo as X →
O f(x) → as x → -- and f(x)
-oo as x - 00

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)

if you need just tell me and i will come to the rescue.

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:
