Each of these equations represents the same function written in different forms.
Standard Form: f(x) = 22 - 2x - 15
Factored Form: f(x) = (2+3)(x - 5)
Vertex Form: f(x) = (2-1)" - 16
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
2 - 2x – 15, because the constant term
shows the zero of the function.
f(x) = (x+3)(x - 5), because you can see when
each factor is equal to zero.
