A graphing calculator is recommended.

For the function, consider the following.

$g(x)=4^x$; find $g(-\frac{1}{2})$

$($a$)$ Evaluate the given expression.

$g(-\frac{1}{2})=$

$($b$)$ Find the domain of the function. $($Enter your answer using interval notation.$)$

$($c$)$ Find the range. $($Hint: Use a graphing calculator. You may have to ignore some false lines on the graph. Graphing in "dot mode" will also eliminate false lines. Enter your answer using interval notation.$)$
