limit as x approaches 7 of (x+7)/(x-7)
Compute the limit of as
ⓘ The limit of a sum of finite limits is the sum of the limits
The limit of is when
⇥Let's calculate:
⇥ⓘ Start from and move forward on the number line: =

ⓘ The limit of a sum of finite limits is the sum of the limits
The limit of is when
⇥Let's evaluate:
⇥ⓘ Start from and move back on the number line, down to zero: =
