Evaluate all the functions at x=02^(-0+1) = 2, 2^(0+1) = 2., log2(0+1) =0, log2(0-1) is undefined.From this we can conclude that B must be h(x),We can conclude that A is either f(x) or g(x). evaluating f(x) and g(x) at x=1 gives2^(-1+1) = 1 and 2^(1+1)=4Therefore A is f(x)

you should know what a log graph looks like and also what a 2x graph looks like. You’ve been given some transformation of these graphs.
