Question

which form most quickly reveals the zeros (or "roots") of the function? choose 1 answer: a. f(x)=-3x^×+12x+15b. f(x)=-3(x+1)(x-5) c. f(x)=-3(x-2)^2+27write one if the zeros:x= ___

Answer 1

B reveals zeros quickly.

Zeros are got from factored form and Option B is in fully factored form.

Now,

Zeros are:

x+1 = 0

x = -1

and

x-5=0

x = 5
