If a polynomial function f(x) has roots 4 – 13i and 5, what must be a factor of f(x)?

(x + (13 – 4i))

(x – (13 + 4i))

(x + (4 + 13i))

(x – (4 + 13i

The answer should be D

factor is (x-(4-13i))

Step-by-step explanation:

If a polynomial function f(x) has roots 4 – 13i and 5

One of the complex root is 4-13i

If we have one complex  root then there should be one more complex  root

complex roots are come in pairs like (a+ib) and  (a-ib)

so another complex root for 4-13i  is 4+13i

If 'a' is a root then factor is (x-a)

4+13i is a root

so factor is (x-(4-13i))

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
