TeX normally typesets summation and product symbols with the indices on the sides in "text" style math fields, but on top/bottom in "display" style math. You can select a math display with
\[...\], which is equivalent to the displaymath environment. If you want it in text mode, but still want display-sized symbols, use the
\displaystyle command (there is also a
\textstyl command). I provide an example of both here.

\Large Exercise 5.1 \normalsize
\\
\\Q1. (a) The graph of $f(x)$ has a domain $D \in [0,8]$, which is divided into four rectangles of equal base, $x = 2$. The actual area under the graph of $f(x)$ isestimted [sic] as: $\sum_{i=1}^{+\infty}{f(x)}$ and $\int_{x_0}^{x_1}$
Option 1:
