What is y=X2-6x+7 in vertex form
alina1380 [7]

Answer:

y = (x - 3^{2}) - 2

Step-by-step explanation:

y = a (x - h)^{2} + k

Standard form: y = ax^{2} + bx = c

Our vertex is: xvertex = - \frac{b}{2a} \\y = x^{2} - 6x + 7 ( STANDARD -  FORM)\\

Finally we get y = (x - 3^{2}) - 2 as our answer.

Have an amazing day!
