Hello, I would like to know how I do a program that request a function [f(x)=], the lower bound [a] and the upper bound [b] as input and after that show me f(a) and f(b).
All I did was:
Request "Input a function:",f ### for exemple x^2+2x-3
Request "Input the lower bound:",a
Request "Input the upper bound:",b
But after that, I don't know how to do "x" be replaced by "a" and "b".
Someone can help?
