Question

What is the vertex of the quadratic function: y=1/2(x-3)2+8?

(3,8)

(-3,-8)

(-3,8)

(3,-8)

Answer 1

(3,8)

Explanation:

THIS IS AN EXAMPLE FOR ANY PROBLEM!!

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. This is the y-coordinate of the vertex.

- Good luck!
