Question

Write the quadratic function in vertex form.

y = x^2 - 6x + 7

Answer 1

Use completion of square method:

\[y = x^2 - 6x + 3^2 - 3^2 + 7\]

\[y = (x-3)^2 - 2\]

Answer 2

thats all u do?

Answer 3

y=x^2-6x+7

Answer 4

Yes..

Answer 5

again the same formula to find the x coordinate of the vertex just use the formula...(i think u know it by now!) then, x = plug that value in the original equation to find y coordinate! y = 3^2 -6(3) + 7... equals -2!
