Question

which ordered pairs are not the graph for h(x)=2x5-4x4-2x2+15?
(-2,7)
(2,7)
(-2,-121)
(2,-121)

Answer 1

sorry.. You should take first number from each pair and then substitute with x in your equation. the pair that doesn't give you 2nd number is the answer

Answer 2

I don't have time to calculate but you can do it.

when you put -2 instead x in the equation will give you 7. look at first pair.

do the same for 2nd pair.

you will find one of pairs does't give 2nd number.
hope that helps
