What is the vertex of the quadratic function f (x) = (x - 3) (x - 2) ?

D

Step-by-step explanation:

Get the equation in the form y = ax2 + bx + c.

Calculate - b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of - b / 2a into the equation for x and solve for y.

- that's how you find the vertex of the quadratic function-
