What is #F(x) = int x-e^(-x) dx# if #F(0) = 2 #? Calculus Techniques of Integration Evaluating the Constant of Integration 1 Answer Mia Sep 15, 2016 #F(x)=x^2/2+e^(-x)+1# Explanation: #F(x)=intx-e^(-x)dx# #F(x)=x^2/2+e^(-x)+C# where C is a constant number Let's find C given #F(0)=2# #F(0)=2# #(0)^2/2+e^(-0)+C=2# #0+1+C=2# #C=2-1# #C=1# Therefore, #F(x)=x^2/2+e^(-x)+1# Answer link Related questions How do you find the constant of integration for #intf'(x)dx# if #f(2)=1#?
