On 1 May 2021, 3,000 people were vaccinated and on 31 May 2021, 45,000 people were
vaccinated.
(a) Setting t =0 on 1 May and t = 30 on 31 May, you want to find a function whose graph
looks similar to the shape above and has the same values of 3,000 at t = 0 and 45,000
at t = 30. In each of (i) to (iv) below solve for the constants a and b so that the given
function goes through the above points at t = 0 and t = 30.
