Minimum cost problem: It cost a company C dollars per hour to operate its base base division. an analyst had determined that C is related to the number of base balls produced per hour, x, by the eqauation C = 0.009x^2 - 1.8^2 + 100. What number of balls per hour should be produced to minimize the cost per hour of manufacturing these base balls?

Solve rational inequality. State and graph the solution set:
3 / x + 2 > 2 / x - 1

Find the vertex and intercepts for each quadratic function:
y = x^2 + 2x - 24
y= -x^2 - 3x - 2

Solve the inequality and state the solution set using interval notation:
x - x^2 less than, equal to zero.
