Question

Cole rewrote a quadratic function in vertex form.
h(x)= x^2−6x+7

Step 1: h(x)= (x^2−6x+ )+7

Step 2: h(x)=(x^2−6x+ 9 )+7 −9

Step 3: h(x)=(x−3 )^2+2

Cole said that the vertex is (3, 2). Is Cole correct? If not, identify the step in which Cole made the mistake and correct his work. step by step

the correct vertex is 3,-2

Answer
so what would be the corrrect steps
Answered by GPT 3.5
Cole is incorrect. The mistake is in Step 2.

Step 1: h(x)= (x^2−6x+ )+7

Step 2: h(x)=(x^2−6x+ 9 )+7 - 9

Step 3: h(x)=(x−3 )^2-2

Therefore, the correct vertex is (3, -2).

Apologies for the confusion in the previous response. Here are the corrected steps to rewrite the quadratic function h(x) = x^2 - 6x + 7 in vertex form:

Step 1: h(x) = x^2 - 6x + 7
Step 2: h(x) = (x^2 - 6x + 9) - 9 + 7
Step 3: h(x) = (x - 3)^2 - 2

Therefore, the correct vertex is (3, -2).
