Question: what is the difference between a rational function and a quadratic function?
Answer: The graph of f(x) plotted against x is a straight line. A quadratic function is of the form f(x) = a*x^2 + b*x + c where a, b and c are constants. ... A rational function f(x) is one that can be written as where P(x) and Q(x) are polynomials of x and Q(x) is not equal to 0.
