# Thread: Graph of y=x^(5/2) and -2x^(1/2)

1. ## Graph of y=x^(5/2) and -2x^(1/2)

Any procedure or guidelines on how to sketch the graph y=x^(5/2) and -2x^(1/2)? I know how it looks like but i had no ideas on the proper procedure of drawing them. Any tips? Thanks.

Sorry, its y=x^(1/3) and not y=x^(5/2)... ^^

2. Try an xy table. Choose values for x, calculate the corresponding y values, and plot the points. You should be able to sketch the graph reasonably.

$f(x)=x^{\frac{1}{3}}$ is the inverse function of $y=x^3$

Sketch $y=x^3$.

What is the relationship between the graph of $y=f(x)$ and $y=f^{-1}(x)$?
