Answer:
The value of f(-2) is 1/2 or it can be written as 0.5.
Step-by-step explanation:
The given function is
[tex]f(x)=2\cdot 2^x[/tex]
We have to find the value of f(-2).
Substitute x=-2 in the given function to find the value of f(-2).
[tex]f(-2)=2\cdot 2^(-2)[/tex]
[tex]f(-2)=2\cdot \frac{1}{2^(2)}[/tex]
[tex]f(-2)=\frac{1}{2}[/tex]
[tex]f(-2)=0.5[/tex]
Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
