9. Again visit http://desmos.com/calculator to construct a new function type, this time using a model which includes an exponential factor and is sometimes called a "surge" function. (a) Into the first equation blank, write Q~a*t *ek*t As in Part 1, the asterisk * will turn into a dot, so what Desmos ought to display is something like: Q~a-1.kt (b) Into the second equation blank, click the "plus" button, and choose "Table". Title your columns t and Q. Again write your input-output pairs into each row of the table. (c) Underneath the formula in the first equation blank, there should now be constants corresponding to the coefficients in the surge function model. Write those constants here: a = 265.621 k= 0.267092 (d) Write the full equation for the surge function, including both constants: 0.267092.t S(t) = 265.621.t.e 10. Let to be the smallest input value in your data set. Let to be the largest input value in your data set. Find the absolute extrema of S(t) on the interval [ta, tb]. vithi nose D CT le
