Which of the following is the equation of the quadratic function below?

It's B.

Step-by-step explanation:

The x intercepts are 2 and 6 so in factor form it is:

y = (x - 2)(x - 6)

y = x^2 - 8x + 12.

Also, to confirm, the y-intercept is at y = 12 which is verified by replacing the x by 0 and working out y:

y = 0^2 - 8(0) + 12

= 12.

B: y=x^2-8x+12

Step-by-step explanation:

For a quadratic function y=ax^2+bx+c,

-b/2a = x-intercept of the vertex

In this question, x-intercept of the vertex=4

-b/2=4 (as in all choices, a=1)

b=-8

or you can simply look at the y-intercept, which is 12 and it equals to the value of c

answer: 486in^2

12 dolars one is cheaper becasue 3 pairs is 6 means is sock is 2 while the 12 is cheaper
