Determine the limit graphically. Confirm algebraically.................

lim (as x approaches 0) of (2+x)^3 - 8/ x

How do you solve this?
I already tried using the table on my calculator. Doesn't give me the answer.
The answer is 12

Next time, use properly parentheses!

limit(((2 + x)^3 - 8)/x, x = 0) = 12

Algebraically,

((2 + x)^3 - 8)/x

diff((2 + x)^3 - 8, x) = 3*(2 + x)^2

diff(x, x) = 1

3*(2 + x)^2 = 3*4 = 12, answer!
