Help me with easy calculus problem

[From: ] [author: ] [Date: 11-10-21] [Hit: ]
Therefore if f(x) = ax+b,then f(x+h) = a(x+h) + b!the limit of (f(x+h)-f(x))/h as h apporaches zero.Good luck in calc!......
this should be easy but it hasnt really hit me...
why if f(x)= ax+b
does f(x+h) = a(x+h)+b

-
When you say f(x) what you are really saying is "function of something". The x in f(x) can be ANYTHING.
For example if f(x)=x+5, then f(obama) = obama +5 lol.
Therefore if f(x) = ax+b,
then f(x+h) = a(x+h) + b!

This is fundamental to the definition of the derivative which is:
the limit of (f(x+h)-f(x))/h as h apporaches zero.

Good luck in calc!
