Problem (1 point Childsmath, 10 points Crowdmark) [1 mark] The number of Canadians (aged 12 and over) who have received at least one dose of COVID-19 vaccine can be modelled by the function V(t) = 7.5Vt+4 -2.5 where Vis millions of Canadians, t is time in months and t = 0 corresponds to May 1, 2021. (a) Sketch the graph of V as a function of t. On your sketch, label the axes and any intercepts or asymptotes. Indicate a reasonable domain. You do not need to identify other points or make your axes to scale. Show your work on Crowdmark. (b) Find a formula for the inverse function of V. Show your work on Crowdmark, including your final answer. (c) At what time t can we predict that 21 million Canadians (aged 12 or older) will have received at least one dose? Show your work on Crowdmark and copy the value of t in the box below, rounded to 3 decimal places if rounding is required
