graph and label the intercepts. y=x^3+2. I know the y intercept is 2

OpenStudy (anonymous):

x intercept solve $0=x^3+2$ $x^3=-2$ $x=\sqrt[3]{-2}$

OpenStudy (anonymous):

looks just like the graph of $y=x^3$ only raised up two units

OpenStudy (anonymous):

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

OpenStudy (anonymous):

oh but it is a "cubed root" not a square root

OpenStudy (anonymous):

a perfectly good real number. for example $\sqrt[3]{-8}=-2$

OpenStudy (anonymous):

only even roots cant have negatives right?

OpenStudy (anonymous):

exactly!

OpenStudy (anonymous):

thanks
