Which polynomial function f(x) has a leading coefficient of 1, roots –4, 2, and 9 with multiplicity 1, and root –5 with multiplicity 3? f(x) = 3(x + 5)(x + 4)(x – 2)(x – 9) f(x) = 3(x – 5)(x – 4)(x + 2)(x + 9) f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x – 2)(x – 9) f(x) = (x – 5)(x – 5)(x – 5)(x – 4)(x + 2)(x + 9)

idk bring the function back   im not smart

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
