Answer:f(2) = 3/2

Step-by-step explanation:

Let u = 2x-1.

Then x = (u+1)/2.

Substituting into f(2x-1) = x, we get f(u) = (u+1)/2.

Thus, f(2) = (2+1)/2 = 3/2.

Do a u-substitution!

Let u = 2x-1.

Then x = (u+1)/2.

Substituting into f(2x-1) = x, we get f(u) = (u+1)/2.

Thus, f(2) = (2+1)/2 = 3/2.
