a limit problem
My professor assigned this problem on page 3 of the link provided and I filled in the table but I don't know how to complete the rest...My guess for B is that the limit of the function as x approaches 0 would equal 0. For C, after trying to simply the equation I get sqrt(x^3)/x^3....is this right? How could I complete part d?

You need to sign in to get to the link. Try writing out and scan it, or by typing it out.

Thanks!

You should fill in the table before you do b.

If you've filled in the table, does it look like the function approaches the same value as you get closer and closer to 0 from both sides?

yeah the table shows that as the function gets closer and closer to 0, the function is 0. The last 3 columns for both positive and negative values were 0. For part c, what would the simplification be? I got sqrt(x^3)/x^3.

0 isn't the limit.

When x is .1, f(x) = -.24998...

x = .01 f(x) = .....
