Question

Which of the following points is in the solution set of y < x2 - 2x - 8?


(-2, -1)

(0, -2)

(4, 0)

Answer 1

\[y<x ^{2}-2x-8 \] ?

Answer 2

that is the equation. which point is in that solution set?

Answer 3

you have to factor out

Answer 4

(x- )(x+ )

Answer 5

just put these values in your equation.....

Answer 6

and then you'll be able to find the solution set (or roots)

Answer 7

try out and i'll help you out

Answer 8

like (4,0) x=4 and y=0
0<4^2-2*4-8
0<16-8-8
0<0
not true
so not the ans like this try other values

Answer 9

Ok. Thank you!
