Please answer! This is my last question:)

Which of the following is a zero for the function f(x) = (x − 15)(x + 1)(x − 10)? (2 points)

1. x = −15
2. x = −10
3. x = 1
4. x = 15

If x=15, then the first factor in the function ... (x - 15) ... is zero,

and then the whole function is zero.


So x=15 is a zero for the function. (Choice-4)
