In your Algebra 2 class, you'll learn how to graph polynomial functions of the form f(x) = x^2 + 5. The f(x), meaning function based on the variable x, is another way of saying y, as in the x-y coordinate graph system. Graph a polynomial function using a graph with an x an...

A third degree polynomial, with two extreme values: peak A and valley B. The peaks and valleys are calledrelative (local) maxima and minima. On a graph, you find extreme values by looking to see where there’s a mountain top (“peak”) or valley floor. ...
What are the Rules to Find the Domain of a Function? Here are some general rules used to find domain of different types of functions: f(x) =polynomial, the domain is the set of all real numbers. f(x) = 1/x, domain if the set of all real numbers but x≠0. ...
Adding a constant shifts the function’s graph to the left that number of units. Splitting a function into two can be useful if the original composite function is too complicated to work with. Composite functions are usually represented by f(x) and g(x), where f(x) is a function that ...
Given a function f(x), find its derivative f′(x). Let f′(x)=0. Solve f′(x)=0 for x. The resulting values of x are the critical points or critical numbers of the function. Consider this example of a polynomial: Example Let f(x)=x3−3x+1. The derivative of f(x) is ...
Practice Problem:Find the domain and range of the function , and graph the function. Solution:The domain of a polynomial is the entire set of real numbers. The limiting factor on the domain for a rational function is the denominator, which cannot be equal to zero. The values...
To find the inverse of a function of x, substitute y for x and x for y in the function, then solve for x.
