Fit a quadratic function to these three points (-1, -11) (0,-3) and (3,-27)

ANSWER

EXPLANATION

Let the quadratic function be

We substitute each point to find the constants, a,b, and c.

Substitute: (x=0,y=-3)

Substitute: (x=-1,y=-11) and c=-3

Substitute: (x=3,y=-27) and c=-3

Add equations (3) and (2)

Put a=-4 in equation (2)

The quadratic equation is

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
