Answer 1

Answer:

Step-by-step explanation:

Step-by-step explanation:

y<2x²+3x-5

Substitute B(1,8)

8< 2*1² +3*2-5

8<2+6-5

8<3 false

B(1,8) is not a solution.

Substitute C(-5,10) in y<2x²+3x-5

10<2*(-5)²+3*-5 -5

10< 50-15-5

10<30 true

C(-5,10) is a solution.

D(3,6)

6<2*3²+3*2-5

6< 18+6-5

6<19 true

D(3,6) is a solution.

E(-3,4)

4<2*(-3)²+3(-3)-5

4< 18-9-5

4<4 false

E(-3,4) is not a solution

F(2,9)

9< 2*2²+3*2-5

9< 8+6-5

9<9 false

F(2,9) is not a solution
