Each of these equations represents the same function written in different forms.

Standard Form: f(x)=x2−10x+24
Factored Form: f(x)=(x−4)(x−6)
Vertex Form: f(x)=(x−5)2−1

The zeros of a function are the values of x for which the function is equal to zero. Which form of the equation makes it easiest to see the zeros of the function?

CLEAR CHECK

f(x)=x2−10x+24, because the constant term shows the zero of the function.

f(x)=(x−4)(x−6), because you can see when each factor is equal to zero.

f(x)=(x−5)2−1, because you can see when the squared expression is equal to zero.

None of these forms, because you can only see the zeros of a function by graphing it.
