Answer 1

Given:

the Function given is,

$f(x)=-4^{(2x+3)}$

To find:

The find the value of the function when x=-1,

$f(-1)$

Explanation:

subsitute the value of x= -1 in the given function,

we get,

$\begin{gathered} f(-1)=-4^{2(-1)+3} \\ =-4^{-2+3} \\ =-4^1 \\ =-4 \end{gathered}$

Final Answer: the answer is -4.
