Given a polynomial f(x), if (x + 7) is a factor, what else must be true? plzzz im running out of time
f(0) = 7
f(0) = −7
f(−7) = 0
f(7) = 0

 f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.
