Question
A linear model estimates that a cat's weight was 4 ounces when it was born and 76 ounces 150 days after it was born. Which function defines this model where f(x) is the cat's weight, in ounces, x days after it was born, for 
?
- f(x) = 0.48 x
- f(x) = 2.08 x
- f(x) = 0.48 x + 4
- f(x) = 2.08 x + 4
The correct answer is: f(x) = 0.48 x + 4
y intercept = 4
On substituting and verifying
Answer = option (C)
