By first principles, the derivative is

Use the binomial theorem to expand the numerator:


where

The first term is eliminated, and the limit is

A power of  in every term of the numerator cancels with
 in every term of the numerator cancels with  in the denominator:
 in the denominator:

Finally, each term containing  approaches 0 as
 approaches 0 as  , and the derivative is
, and the derivative is

Answer:
300
Step-by-step explanation:
4=25%
12=1200
12/4=3
add the zeroes from 1200
300
to make sure...
300x4=1200
 
        
             
        
        
        
I think the last two are correct.
Hope it helps
        
             
        
        
        
m = (y2-y1)/(x2-x1)
m = (6-4)/(4-0)
m = 2/4
y = mx + c
6 = (2/4)(4) + c
c = 4
Thus, the equation is y = (2/4)x +4
