If a polynomial function f(x) has roots -9 and 7-i, what must be a factor of f(x) (x-(7+i))
(x-(-7-i))
(x+(7+i))
(x+(7-i))

Step-by-step explanation:

For a polynomial with roots and , the polynomial can be written in factored form . That way, when you plug in any of the roots, returns zero.

Since the polynomial has at least two roots-9 and 7-i, two of its factors must then be:

Therefore, the desired answer is

y=mx+b

step-by-step explanation:

m slope, b y-intercept

its an acute right triangle
