The difference quotient is calculated as:

Calculate f(x + h)



The numerator of
is:


Collect like terms


So, we have:

Rewrite as:


Answer:
100 i think
Step-by-step explanation:
30%.
Well, the simplest way to do it is to put it as a fraction.
90/300.
This is the same as 3/10, which is the same as .30, which is the same as 30% :P
Hope this helped!
