(PLEASE ANSWER QUICK) (10 points )

WHICH OF THE FOLLOWING IS THE FUNCTION FOR THE GRAPH SHOWN?

Answer 1

C. y=x^2-6x+8

Explanation:

We have to check each functions in options with the given point

So,

The point is (3,-1)

For A:

`y = x^2+6x+8\\Putting\ the\ point\\-1 = (3)^2+6(3)+8\\ -1=9+18+8\\-1 \\eq 35`

For B:

`y=x^2-2x-8\\-1 = (3)^2-2(3)-8\\-1=9-6-8\\-1\\eq -5`

For C:

`y = x^2 - 6x+8\\-1 =(3)^2-6(3)+8\\-1= 9-18+8\\-1=-1`

The given point satisfies the third function. Therefore, Option C is the correct answer ..
