Question

Find the solutions to 0 ≥ x4 – 1 by graphing y ≥ x4 – 1 by hand.

I keep checking it in wolfram alpha and I keep getting it wrong.

Answer 1

what do you get?

Answer 2

I just made an x/y table, which does not graph into a parabola like it's supposed to.
-2| -17
-1| -2
0| -1
1| 0
2| 15

Answer 3

(-2)^4 = (2)^4

Answer 4

so f(2) and f(-2) should be the same

Answer 5

Thanks, I got it now.
