Question 1125762
<font face="Times New Roman" size="+2">


Given a function *[tex \Large \phi(x)], the average rate of change from *[tex \Large x_a] to *[tex \Large x_b] is equal to the slope of the line through *[tex \Large \(x_a,\phi(x_a)\)] and *[tex \Large \(x_b,\phi(x_b)\)], which is calculated by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{\phi(x_b)\ -\ \phi(x_a)}{x_b -\ x_a}]


Your parts a, b, and c are just three arithmetic problems.  You can use a calculator just as well as I can.

My calculator said it, I believe it, that settles it
