Question

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

Answer 1

See below in bold.

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.
