Question

Which of the following describes the roots of the polynomial function f (x) = (x + 2) squared (x minus 4) (x + 1) cubed?

Answer 1

Are there any answer choices?

Answer 2

Because it does say which of the following

Answer 3

–2 with multiplicity 2, 4 with multiplicity 1, and –1 with multiplicity 3
–2 with multiplicity 3, 4 with multiplicity 2, and –1 with multiplicity 4
2 with multiplicity 2, –4 with multiplicity 1, and 1 with multiplicity 3
2 with multiplicity 3, –4 with multiplicity 2, and 1 with multiplicity 4

Answer 4

(x+2)^2(x-4)(x+1)^3
now first we have to find our roots. Do you know what the roots of the function are?

Answer 5

no

Answer 6

take a function, something like lets say y =(x+2)(x+6).
The x-intercepts are your roots, so in the case of y = (x+2)(x+6), your roots are -2 and -6

Answer 7

So A is really the move?

Answer 8

You got it
