Extracted text: Let f(x) = ex. 1- Write a C++ program to find the approximations to f'(2.3) using central-difference formula of order O(h?) with h=0.1, h=0.01, and h=0.001. You need to print a table like Table 6.2 and to find optimum step size from the table (minimum error). 2- Complete your program by comparing your results in part 1 with the value f'(2.3)=e23. 3- Repeat part 1 using central-difference formula of order O(h*).
