Question

Solve the inequality \[x^4 ge x^2\] and express the solution as an interval.

Answer 1

\[x^4 \ge x^2\] \[x^4 - x^2\ge 0\]

Answer 2

x^4 is greater than or equal to x^2?
x is a function of all real numbers....
(-inf,inf)

Answer 3

wait....I'm sorry...I messed up.

Answer 4

x^4 is greater than or equal to x^2
I believe this means that x has to be greater than or equal to 1

Answer 5

For example....
(1/2)^4=1/16
(1/2)^2=1/4

Answer 6

For the interval I got [-1,0) U [1,infinity)

Answer 7

it would be (-inf,-1] U [1, inf)

Answer 8

can you take it from here?
