## Intermediate Algebra: Connecting Concepts through Application

$(4, +\infty)$
The interval begins at, but does not include, $4$. This means that a parenthesis will be used on the left part of the interval notation. The interval goes all the way to the right without bound, so the interval goes to positive infinity. This means that a parenthesis will be used on the right end of the interval. Therefore the interval notation of the given interval is $(4, +\infty)$.
