+38 I need some help, people

i think in real numbers it should be x>0 && x<2 but i im really not sure.
When I get 2^x=t - substitution then it will be t^2-3*t-4<0 so roots are 4, -1 but i think that t it should be R+ (0,infinity) because the exponencial function's range is (0,infinity), so t is 4 and then t<4 so x<2 but I dont know (0,2) or (-infinity, 2)
