In a science experiment, a quantity Q(t) was observed at various points in time t. Time is measured in seconds from the instant of the first observation. The table below gives the results. 2. 3 4. 2-920 2-642 2-391 2-163 1-957 O follows a rule of the form Q(t) = Ae, where A and b are constants. (a) Use any two of the observations from the table to find the value of A and the value of b, correct to three decimal places. (b) Use a different observation from the table to verify your values for A and b.
