Question

PLEASE HELP WILL GIVE A MEDAL
Find the limit of the function by using direct substitution.

Answer 1

\(\large\color{slate}{\displaystyle\lim_{x \rightarrow ~1}f(x)}\) is what you need.

To find \(\large\color{slate}{\displaystyle\lim_{x \rightarrow ~1^-}f(x)}\) plug in 1, into x-1.

To find \(\large\color{slate}{\displaystyle\lim_{x \rightarrow ~1^+}f(x)}\) plug in 1 into x+7

Answer 2

if 2 sides of the limit are not equivalent, then the limit does not exist.
