Question

Complete the standard form equation representing the quadratic relationship displayed above, where a, b, and c are constants.

Answer 1

y = -2x2 + 8x + 5.

Explanation:

Answer 2

Y =-10X +5

Explanation:

x1 y1 x2 y2

1 -5 0 5

(Y2-Y1) (5)-(-5)= 10 ΔY 10

(X2-X1) (0)-(1)= -1 ΔX -1

slope= -10

B= 5

Y =-10X +5
