Answer:
The value of f(x) when x=-1 is 0.5
Therefore [tex]f(-1)=0.5[/tex]
Step-by-step explanation:
Given that y=f(x)=[tex]2^x[/tex]
to find the f(x) when x=-1 :
That is to find f(-1)
Put x=-1 in the given function f(x)=[tex]2^x[/tex]
[tex]f(-1)=2^{-1}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]=0.5[/tex]
Therefore [tex]f(-1)=0.5[/tex]
The value of f(x) when x=-1 is 0.5
