find the a, b,c of this table

a = b = 1 , c = - 8

Step-by-step explanation:

ax² + bx + c = y

( - 5 )² a - 5b + c = 12

c = - 8

3² a + 3b + c = 4

25a - 5b - 8 = 12 ⇔ 25a - 5b = 20 ⇔ 5a - b = 4 (1)

9a + 3b - 8 = 4 ⇔ 9a + 3b = 12 ⇔ 3a + b = 4 (2)

(1) + (2)

8a = 8 ; a = 1

b = 1

b.an increase in a causes b to decrease

9 x 8 divided by (5-3)=36
