Which second degree polynomial function has a leading coefficient of -1 and root 4 with multiplicity 2? O f(x) = -x2 – 8x – 16 O

Question

Which second degree polynomial function has a leading coefficient of -1 and root 4 with multiplicity 2?
O f(x) = -x2 – 8x – 16
O f(x) = -x2 + 8x – 16
o f(x) = -x2 – 8x + 16
Of(x) = _x2 + 8x + 16

    Answer:

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

    Step-by-step explanation:

    we know that

    A polynomial function that has a leading coefficient of -1 and root 4 with multiplicity 2 is equal to

    f(x)=-(x-4)^{2}

    Expand the function

    f(x)=-(x^{2}-8x+16)\\ \\f(x)=-x^{2} +8x-16
