When I graph a cubic function, all the positive x-values are being shown. However, all of the points that have a negative x-value are not being shown on the graph. Does anyone have a solution to this?

Yep, i tried it. I put in my equation as x^1/3, maybe that is the problem?

screen 1 ... entering y = x^(1/3)

screen 2 ... how it looks after you enter it

screen 3 ... graph of x^(1/3) in a decimal window
