0 Recall that e is an important constant that shows up in many branches of mathematics. It is an irrational number. Does
the behavior of f(x) = ei look any different than f(x) = b', where bis a positive integer greater than 1?

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
