What is a Function?
A function assigns the value of each element of one set to the other specific element of another set.
To know which graph represents the function f(x)=2⁻ˣ, substitute the value of x as 0, 1, 2. And check it with the function.
f(0) = 2⁰ = 1
f(1) = 2⁻¹ = 1/(2¹) = 0.5
f(2) = 2⁻² = 1/(2²) = 0.25
Hence, the correct option is B (Second graph).
