QuestionThe following exponential function models the number of students who are ill with Covid as a result of infection by other students in a large lecture section: $$N(t)=3\left(1.3^{\frac{t}{4}}\right)$$ $N$ is the number of infected students and $t$ is the number of days after the initial exposure. Answer the following questions:
Is this a growth or decay function? Type growth or decay: $\square$ A
The percentage increase in Covid cases is $\square$ A in how many days? $\square$ A
How many students were infected initially? $\square$ $\Delta$
