What M value should I use? (how do i find it)

I was asked to calculate the area between two functions, y=e^x and y=x using midpoint riemann sums from 0-2 with n=4. so i found my answer by subtracting the second sum from the first.
The second question asks me to find a bound for the absolute error. I need to plug things into Em=M(b-a)^3/24n^2 but I don't understand if i should use e^x to find the max value of f''(x) or y=x? or both?
