Suppose your dog weighted 2.7 pounds at birth and weighed 28 pounds one year
later.
a. Based on these two data points, find a linear function that describes how weight varies with age.
let x = the age
f(x) = weight
f(x) = ax + 2.7
x=1, f(x) = 28
1a + 2.7 = 28
a = 28-2.7
a = 25.3
f(x) = 25.3x + 2.7
:
b. Use the equation (your answer to part a) to predict your dog�s weight at 5 yrs
f(x) = 25.3(5) + 2.7
f(x) = 126.5 + 2.7
f(x) = 129 lb
;
and 11 yrs old
f(x) = 25.3(11) + 2.7
f(x) = 278.3 + 2.7
f(x) = 281 lb

Obviously not of the real world, animal growth is certainly not linear
