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

  f(x) = -x^2 +8x -16

Step-by-step 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

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
