A taxi charges $3 per passenger. The function $R(n) = 3n$ gives total revenue in dollars when $n$ passengers ride. The taxi holds at most 4 passengers. Which best describes how to graph $R$ on its contextual domain?

Draw a solid line through the origin with slope 3.

Draw isolated dots at $n = 0, 1, 2, 3, 4$ .

Draw a ray starting at the origin extending to the right.

Draw a solid line from $( 0, 0 )$ to $( 4, 12 )$ .
