A model predicts that a certain elephant calf weighed 249 pounds when it was born and that the calf gained 2 pounds per day in its first year of life. This model is defined by an equation in the form $f(x)=a+bx$, where $f(x)$ is the predicted weight, in pounds, of the elephant calf $x$ days after it was born, and $a$ and $b$ are constants. What is the value of $a$?
