The zeros of a quadratic function are 6 and -4. Which of these choices could be the function? A.
f(x) = (x − 6)(x + 4)
B.
f(x) = (x + 6)(x − 4)
C.
f(x) = (x − 6)(x − 4)
D.
f(x) = (x + 6)(x + 4)

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
