Nyelo! Welcome to QuestionCove cx I'll be helping yew for dis problem >.<

You are told that he increases his workouts by adding 2 miles a month, this means each month, so the 1st month has 2.5 miles, 2nd has 4.5 and so on and so forth.

Looking at the equation you have $\bf{f(x)=0.5+2x}$ It is in the format of $\bf{y=mx+b}$ meaning that $\bf{0.5}$ is your start, and $\bf{2}$ is your rate. This would mean that $\bf{x}$ would equal to `each month`. Understand?
