what are polynomial functions
Recall that f(3) can be found by evaluating the. function for x 3. A polynomial equation used to represent a function is called a. . For example, the equation f( x) 4 2 5 2 is a quadratic polynomial. function, and the equation p(x) 2x3 4x2 5x 7 is a cubic polynomial function. Other polynomial functions can be defined by the following general rule.
