Representing Functions Summary 6 2 M 08 BF

Representing Functions Summary 6. 2 M 08. B-F. 1. 1. 2 Compare properties of two functions, each represented in a different way.

Linear Function: A function with all points on the same line. Nonlinear Function: A function with points not all on the same line.

Discrete Graph: A graph where points are not connected. Continuous Graph: A graph where points are connected.

Domain and range for a discrete function: Make a list Domain: Set of x-values {1, 2, 4, 5} Write the Range: Set of y-values { } Is this graph linear?

Domain and range for a discrete function: Make a list Domain: {1, 2, 4, 5} Range: {1, 3, 4, 5} This graph is not linear because you cannot draw a straight line through all the points.

Domain and Range for a Continuous Function Use inequalities Domain: Set of x-values (left to right) {-5 ≤ x ≤ 6} Write the Range: Set of y-values (bottom to top) { }

Domain and Range for a Continuous Function Use inequalities Domain: Set of x-values (left to right) {-5 ≤ x ≤ 6} Range: Set of y-values (bottom to top) {-3 ≤ y ≤ 8}

The independent variable is found on the x-axis. The dependent variable is found on the y-axis.

How much does it cost to get your car washed? Should this graph be discrete or continuous? Why?

The cost of a car wash is $10. The graph is discrete. You can’t pay $5 and get half your car washed.

Is this graph linear or nonlinear? Find the equation of this function.

The slope of the line is ____, the y-intercept of the line is ____, and the equation of the line is ________.

y = 10 x Use the equation to find the amount earned for washing 20 cars.
