We will start with the graph of the standard/parent function y=x
The graph of y=kf(x) is obtained by vertically stretching the graph of y=f(x) by a factor of k.
Therefore, if we vertically stretch the graph of y=x by a factor of 2, we will get the graph of y=2x
In the graph below:
The blue dashed curve represents y=x
The red solid curve represents y=2x

Suppose you take a dose of m mg of a particular medication once per day. Assume f equals the fraction of the medication that remains in your blood one day later. Just after taking another dose of medication on the second day, the amount of medication in your blood equals the sum of the second dose and the fraction of the first dose remaining in your blood, which is m+mf. Continuing in this fashion, the amount of medication in your blood just after your nth does is An=m+mf++mfn1. For the given values off and m, calculate A5,A10,A30, and limnAn. Interpret the meaning of the limit limnAn. f=0.25,m=200mg.

The process by which we determine limits of rational functions applies equally well to ratios containing noninteger or negative powers of x: Divide numerator and denominator by the highest power of x in the denominator and proceed from there. Find the limits. limxx34x2+25
