x intercept solve \[0=x^3+2\] \[x^3=-2\] \[x=\sqrt[3]{-2}\]
looks just like the graph of \[y=x^3\] only raised up two units
okay, thats what i had i just wanted to be sure it was right, it just looked weird and i wasn't positive about it having the negative under the radical
oh but it is a "cubed root" not a square root
a perfectly good real number. for example \[\sqrt[3]{-8}=-2\]
