Given a polynomial f(x), if (x + 3) is a factor, what else must be true?

f(3) = 0
f(-3) = 0
f(0) = 3
f(0) = -3

Step-by-step explanation:

we know that

The zero of a function is the value of x when the value of the function is equal to zero

In this problem

If is a factor of a polynomial

then

is a zero of the polynomial

so

For ------->

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
