Question

How do I graph a fourth-root power function on a graphing calculator?

Answer 1

Use the exponent `1/4`.

Explanation:

Recall that `root(b)(x^a)=x^(a/b)`.

That means that `root(4)(x)=x^(1/4)`.

Just remember while graphing to put parentheses around `(1/4)` if you're using it as an exponent.
