Real World Quadratic Functions Maximum profit. A chain store manager has been told by the main office that daily profit‚ P‚ is related to the number of clerks working that day‚ x‚ according to the function P = −25x2 + 300x. What number of clerks will maximize the profit‚ and what is the maximum possible profit? In order to find the point at which profit is maximized‚ I must find the critical points of the first derivative of the equation. Coefficient of x^2 is negative‚ so

When you are graphing quadratics‚ it is the same as graphing linear equations but‚ quadratics have the curvy line‚ called a parabola. When you are graphing your points‚ it is best to graph three or more points. You are really going to need to point three or more points‚ because if there are less than three you will not have a correct graph‚ graphing more than three will insure that your graph will be correct. The biggest number that they say you have to graph will most likely not be able to be graphed

Quadratic functions are used all the time‚ every day‚ all over the world. Even though right now‚ it doesn’t seem like this kind of math is ever going to creep back into our life. That is actually far from true. These math skill are crucial to have if one ever decides to do anything in engineering‚ or something like that. Those types of jobs are now becoming more and more popular‚ because the world is always going to need educated people who know how to construct or refurbish buildings and homes.
