A farmer decides to take up breeding cows. He decides he will buy 7 more cows each year.

Answer:

200 cows

Step-by-step explanation:

7n+x=340 where n equals the number of years and x is the starting amount. Since he has been buying cows for 20 years, we plug 20 in for n. This would give you 140+x=340. After subtracting 140 from both sides you come to the conclusion that x=200.

The vertical change from 1 to 5 is considerably less for g(x) than for f(x).
