Please solve the problem and give me a detailed explanation.

Thanks!

Suppose \( c \) is an unknown number (but not a variable). Consider the following function:

\[
h(x) = 
\begin{cases} 
\frac{1}{4}c^2x^2 + 3, & x < 2 \\
c + 9, & x = 2 \\
c^2x^2, & x > 2 
\end{cases}
\]

Find the value(s) of \( c \) that makes \(\lim_{x \to 2} h(x)\) exist. Use algebra, not a graph to justify your reasoning, though you may use a graph to check your work.
