1. a) a maximum or minimum is given for each of the following functions. Select a strategy and verify whether the point given is a max or a min.

a) f(x)= x^2-10x+7 ; (5,-18)

2. For each function find the equation for the slope of the secant line between any general point on the function (a+h, f(a+h)) and the given x-coordinate of another point

a) f(x)= x^2 -30x a=2
