Question

Which point is not on the graph represented by y = x^2 + 3x - 6?

(1) (-6,12) (3) (2,4)
(2) (-4,-2) (4) (3,-6)

Answer 1

Explanation:

the answe would be 3,-6 because it just makes sense and you should know bc it common math and yeah get better

Answer 2

`y=x^2+3x-6`

Plug the values (x,y) into the equation and check if they satisfy it.

`1. (-6,12) \\ 12=(-6)^2+3 * (-6)-6 \\ 12=36-18-6 \\ 12=12 \\ true \\ \\ 2. (-4,-2) \\ -2=(-4)^2+3 * (-4)-6 \\ -2=16-12-6 \\ -2=-2 \\ true`


`3. (2,4) \\ 4=2^2+3 * 2-6 \\ 4=4+6-6 \\ 4=4 \\ true \\ \\ 4. (3,-6) \\ -6=3^2+3 * 3-6 \\ -6=9+9-6 \\ -6=12 \\ not \ true`

The answer is (4).
