Answer

The graph is shown in the solution part.

Work Step by Step

A point of the graph is in the form $(t, N(t))$. The answers to exercise 127 are a. one person. b. 10 persons. Convert the answers into points on the graph. a. At the initial moment ($t=0$) the number of persons who started the rumor is $1$, so $N(0)=1$. The corresponding point on the graph is $(0,1)$. b. After $4$ minutes ($t=4$), the number of people who heard the rumor is $10$ ($N(4)=10$). The corresponding point on the graph is $(4,10)$ Now plot these points on the graph as shown below.
