What is #f(x) = int x-3e^(x)dx# if #f(0)=-2 #? Calculus Techniques of Integration Evaluating the Constant of Integration 1 Answer Cem Sentin Dec 20, 2017 #f(x)=x^2/2-3e^x+1# Explanation: #f(x)=int (x-3e^x)*dx=x^2/2-3e^x+C# After imposing #f(0)=-2# condition, I found #C-3=-2#, so #C=1# Thus, #f(x)=x^2/2-3e^x+1# Answer link Related questions How do you find the constant of integration for #intf'(x)dx# if #f(2)=1#?
