Question

The inequality –x2 + x – 10 < – 2x2 – 4 is satisfied if...

Answer 1

\[-x ^{2}+x-10<-2x ^{2}-4\]

Answer 2

\[x^2-x-6<0\]
\[(x-3)(x+2)<0\] and since this is a parabola that opens up, it will be negative between the zeros so answer is
\[(-2,3)\]

Answer 3

x^2+x-6<0 ===> (x-2)(x+3) <0 ==> solution interval = (2,3)

Answer 4

I mean (-3,2)

Answer 5

The answer key says -3<x<2.

Answer 6

raheen is right i am wrong i wrote -x when it should be +x

Answer 7

I guess I was supposed to use the coordinates to make an inequality statement

Answer 8

no no that is not a coordinate!

Answer 9

Ah, right, because they're both domains

Answer 10

thats means
\[\{x|-3<x<2\}\]

Answer 11

Yes, thanks for your help :)
