(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For the limit below, find values of δ that correspond to the ε values.

2. Relevant equations

epsilon = .5

and

epsilon = .05

3. The attempt at a solution

These kinds of problems do you have to use a graphing calculator to figure it out?

for epsilon = .05

|(9x + x - 3x^3)-7|<.05

6.95<(9+x-3x^3)<7.05

and I graph it, i get x = about -.75548, y=6.95

x = -.73803, y=7.05

i get |x-1|<0.2619

but its incorrect
