Math Help - Modulus x^n

1. Modulus x^n

I'm having problems visualising this graph...my calculator won't plot it, neither will Wolfram

$y = |x^n|$ where n is a positive constant

Here's the question

$\int_{-2}^{2}|x^n|dy$

It looks like an exponential, but I'm not sure how that translates in modulus form.

Here's the question $\int_{-2}^{2}|x^n|dx$

There are a couple difficulities with this question.

1) In n is a positive integer then it is easy: $2\int_{0}^{2}x^ndx$

2) But if n could be one-half what about negative numbers to the one-half power.
Are we to use complex roots?

Here's the question

$\int_{-2}^{2}|x^n|dy$ ... dy ?

since $y = |x^n| \ge 0$ for all $n > 0$, and the lower limit of integration is -2, are you sure that the integration is w/r to y ?
