Use the intersect command on a graphing utility to solve the following equation for the indicated value of b.

X^3-218x=b

b=2504

Can you please give me the exact steps of how to do it on calculator?

i typed the below equation into the "y=..." page of my TI-84 Plus.

y=... X^3-218x-2504

Then i go on "2nd--calc", press "intersect" command AND keep on getting error on the screen!?
