Text becomes justified with wrapfig

Here is my documnet:

My text is being justified and it’s leaving large spaces – how do I get rid of it. Here is my code:

documentclass{article}
begin{document}
begin{wrapfigure}{h!}{0.4textwidth}
    includegraphics[width=0.4textwidth]{epsilon-delta.jpg}
    label{fig:example_graph}
    caption{this graph shows possible values of  $delta$ for various choices of $varepsilon>0$  for a given function $f(x$), a number $a$, and a limit $L$ at $a$. Note: $delta pm a$ does not need to map onto $L pm varepsilon$ through $f$.}
end{wrapfigure} %figure wrapping problem

which means the limit of the function  $f$, as  $x$  approaches  $c$, is $L$ iff for all distances away from $L$, $varepsilon$, there exist a distance from $c$, $delta$, such that if $x$ is within $delta$ of $c$ (but not at $c$) $f(x)$ is within $varepsilon$ of $L$.\

It also states that  for all $x in (c-delta,c+delta) cap  text{dom}_{f} $ there exist a $y in (L-varepsilon,L+varepsilon)$ such that $y=f(x)$. %evaluate usefulness

Remember:\
$0 < |x-c| < delta$ is equivalent to $ c - delta < x < c + delta text{, } x neq c$ and $|f(x) - L| < varepsilon$ is equivalent to $L - varepsilon < f(x) < L + varepsilon$\
