2018-2019 WS CH 2.2.1 Graphing Functions 2 GRAPHING FUNCTIONS Find the domain of ? ? = 4−3𝑥 2𝑥+5 Solution : The given rational expression is defined for every ? except those that make the denominator 0 ∴ The domain of ? is all values of ? except − 5 2 or −∞, − 5 2 5 2 , ∞
2018-2019 WS CH 2.2.1 Graphing Functions 3 The domain of a function is the set of all the ? − coordinates of points on the graph of the function The set of all real numbers for which the expression is defined as real number The range of a function is the set of all the ? − coordinates of points on the graph of the function To describe the domain and range of a function use the interval notation The solid dot is used to indicate that a point is on the graph of the function The open dot is used to indicate that a point is not on the graph of the function

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
