Aparabola passes through the points (-2,8), (0,2), and (1,5). what function does the graph represent?

ANSWER

EXPLANATION

Let the function that represent the graph be:

The parabola passes through the points (-2,8), (0,2), and (1,5).

These points must satisfy the function.

For (-2,8), we have

This implies that that,

For (0,2), we have,

This implies that,

For (1,5), we have

This implies that,

Put c=2 into equation (1) and (2).

Add equation (3) and equation (4)

Put a=2 into equation (4).

Therefore the function is
