2.6

Step-by-step explanation:

Step-by-step explanation: That would mean that f(2) and f(4) both equal 3, and one-to-one ... the function defined by f(x)=2x + 2, and let g : R ! R be the function defined by g(x) = 1. 2 x 1. Then ... Use that f is an invertible function and that f-1. (1) = -2 f-1(2) = 3 f-1(3) = 2 f-1(4) = 5 f-1.
