Question

How do you graph the function f(x)= -1/2x^3?

Answer 1

Start with a table of values. Note that f(x) goes to infinity when x goes to 0 (assuming you meant -1/(2x^3) instead of what you wrote), so there will be an asymptote as x->0 (which is the y axis)

Answer 2

Sorry. It's (1/2)x^3.

Answer 3

OK, same advice, but no asymptote.

Answer 4

You can also use a program called winplot
Download it, it's free, and it helps with giving you the zero's, intercepts and what not.

Answer 5

ok thank you all.
