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)`

Step-by-step 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.
