WebMay 31, 2014 · A linear solution to a problem would be an algorithm which execution times scales lineary with n, so x*n + y, where x and y are real numbers. n appears with a highest exponent of 1: n = n^1. With a quadratic solution, n appears in a term with 2 as the highest exponent, e.g. x*n^2 + y*n + z. For arbitrary n, the linear solution grows in ... WebSolution method 1: The graphical approach. It turns out graphs are really useful in studying the range of a function. Fortunately, we are pretty skilled at graphing quadratic functions. Here is the graph of y=f (x) y =f (x). Now it's clearly visible that y=9 y=9 is not a possible output, since the graph never intersects the line y=9 y=9.
