Answer
In summation we can write the function as:
$h(n)=\begin{cases}2, for: 1\le n\le 5\\ 5, for: 5\lt n\le 7\end{cases}$
Work Step by Step
As h is the function of the day of the week, the function will be:
$h(n)$, and it is a piece wise function.
The domain is $1\le n\le7$, where $n$ is an integer.
As during the week we only read 2 hours per day:
If $1\le n\le 5$ $h(n)=2$
As during the weekend we read 5 hours per day:
If $5\lt n\le 7$ $h(n)=5$
In summation we can write the function as:
$h(n)=\begin{cases}2, for: 1\le n\le 5\\ 5, for: 5\lt n\le 7\end{cases}$
