Answer:
0 ≤ v ≤ 230
Step-by-step explanation:
The function E(v)=50+2v models the amount of money Roger earns by selling v videos.
Roger is paid $50 to sell videos of a play to an audience after the play is performed. He also receives $2 for each video he sells.
Now, it is given that the play's audience consist of 230 people and each audience member buys no more than 1 video.
Therefore, the domain of the function will be given by
0 ≤ v ≤ 230
here v = 0 when each audience buys zero video and v = 230 when each audience buys 1 video. (Answer)
