The function f(x) =1/2 (2)^x is the exponential equation of the graph, the correct option is B.
What is an Exponential Function?
An exponential function can be represented in the form f(x) = abˣ.
It passes through the points (1,1), (0,0.5) and (-1,0.25)
f(x)=2(1/2)^x
f(x) = 2 (1/2)⁰
f(x)= 2 ( not satisfied)
f(x) = 1/2 (2)^x
f(x) = (1/2) 2⁰
f(x) = (1/2)
f(x) = (1/2)2⁻¹
f(x) = 0.25
It satisfies all the values
