Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
a zero of the function is a value of x that makes the value of the function zero ... factoring gives f(x)=(x+7)(x-1)

so the zeroes of the function are -7 and 1; because each of these values causes one of the multiplicands to be zero, giving a zero value for the product, f(x)
