Question

which second-degree polynomial function has a leading coefficient of -1 and root 4 with multiplicity 2

Answer 1

f(x) = -x^2 +8x -16

Explanation:

With the given data, we can write the factored function as ...

f(x) = -1(x -4)^2 . . . . . -1 is the leading coefficient; exponent of 2 gives root multiplicity

f(x) = -x^2 +8x -16
