2. The scatterplot below shows the amount of time a trumpet player spends practicing a song, and the
number of incorrect notes she plays while performing that song. Based on this graph how many incorrect notes will she play if the practice time is 7 1/2 hours?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
