Witch of the following is a zero for the function f (x) = (x-15) (x+1) (x-10)

See below in bold.

Step-by-step explanation:

f (x) = (x-15) (x+1) (x-10) = 0

The zeroes of the function are found as follows:

x - 15 = 0, so x = 15.

x + 1 = 0 and x - 10 = 0.

- in the same way - 1 and 10 are also zeroes.
