Since the given function is zero for negative t, we only need to integrate from zero to infinity to find C.

∫_{0}^{∞}Ce^{-2t}dt = 1

(Ce^{-2t})/(-2) |_{0}^{∞} = 1

(-C/2)(0 - 1) = 1

C/2 = 1

**C = 2**

thank you so much for help, but i need you to explain by more steps how this (Ce-2t)/(-2) |0∞ = 1. became (-C/2)(0 - 1) = 105/12/20
