My second course in analysis and i have a problem which i can't understand
Let f (x) = 1 if 2<=x<4
2 if x =4
-3, if 4<x<=7
Prove that this function is integrable on [2,7], state its value and prove that it is what you say it is.
Obviously integral of f from [2,7] is -7. but its proof and the integrability have me and my friends snagged.
Suggestions anyone?
