If you know the zeros of a quadratic function, how do you locate the vertex? (Site 2)

,  ( zeros of the polynomial)

Step-by-step explanation:

Given the zeros of a polynomial, , to determine the vertex, follow these steps.

Find the equation of symmetry x=h where

Substitute the value of h into the quadratic function f(x) to find the maximum of minimum point.

Therefore, the coordinate of the vertex will be:

sorry, i don't know i just need points, i'm new here. chao

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
