The graph shows the number of people infected with a virus as a function of time. the graph shows exponential a- decay b- growth as the amount of people infected with the virus decreases, time a- increases b- decreases

The graph shows exponential B

exponential decay is when the graph is decreasing/going down

exponential growth is when the graph is increasing/going up

The graph is shown to be increasing, so it is exponential growth

As the amount of people infected with the virus decreases, time B

If you look at the graph, as time increases, the number of infected people also increases. So when the # of infected ppl decreases, so does time

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

$12. that is my answer.
