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
