Evaluate the function below. Round to four decimal places, if necessary. f(x)=-4^{2x+3} , for f(-1)f(-1)= Answer

Given:
the Function given is,
[tex]f(x)=-4^{(2x+3)}[/tex]To find:
The find the value of the function when x=-1,
[tex]f(-1)[/tex]Explanation:
subsitute the value of x= -1 in the given function,
we get,
[tex]\begin{gathered} f(-1)=-4^{2(-1)+3} \\ =-4^{-2+3} \\ =-4^1 \\ =-4 \end{gathered}[/tex]
Final Answer: the answer is -4.
