Continuity in cube root functions

Exercise No. 1 from page 26.

Find values of x, if any, at which f(x) is not continuous.

Answer: None because as you can see the graph (below) of this function is continuous everywhere.

I am showing the graph above because i don't think most of you know how the function of cube root looks like. So here, I put a little bit effort more than you guys to find the graph and to show it to you. I hope this will give you an idea on how a cube root function looks like.

Look at the x-intercept. The graph cuts at x = -6 since our function is (x+6).

Can you guess how will this function looks like?
