Key Terms
 Extreme Value – A value of the function y = f(x) that is the greatest or least value of y.
 The greatest value is called the maximum, and the least value is called the minimum.
 Graph of the Polynomial – The graph of an equation in which the right side is a polynomial.
 The graph is a curve with no breaks or sharp corners.
 Maximum – The highest point on the graph of a function, or the greatest value in a data set.
 Minimum – The lowest point on the graph of a function, or the smallest value in a data set.
 Roots – Values for which a function equals zero.
 The roots are also called zeros of the function.
 Any xvalue at which the graph of a function crosses the xaxis is a root of the function.
 A root is shown on a graph when the yvalue equals zero (y = 0)
 Ex. (4, 0), (3.2, 0), (100, 0), etc.
