Identifying Functions from Ordered Pairs
Multifaceted practice awaits you in these 8th grade math worksheets. Observe each set of ordered pairs given in Part A, figure out ordered pairs from graphs in Part B, and state if they represent a function.
Identifying Linear and Nonlinear Functions from Equations
Examine each function equation and decide if it is linear or nonlinear. Functions are linear if they do not have an exponent.
Write the Domain and Range from Ordered Pairs
Figure out the domain and range for each set of ordered pairs in the first half. In the second half, determine the same from the graph.
Peer through the function table and evaluate f(x) for each value of x, find g(x), and determine the value of x, when f(x) or g(x) is given.
Is the Function Linear or Nonlinear? | Graph
The graph of a linear function is a straight line. Use this fact, inspect each graph, and identify the linear and nonlinear functions.
Analyze and compare each pair of linear functions presented as graphs, tables, or equations and answer the questions.
Plug in the value of x in the function rule f(x) and evaluate for a specified value of x. Solve expressions with arithmetic operations.
Graphing Linear Functions | Type 1
Input the values of x in the function rule to generate f(x) and complete the function tables. Plot the values and graph the line.
Identifying Functions | Relation - Table
Scrutinize each function table, there should be only one output for every input and no repeated values for a relation to be a function.
Graphing Linear Functions | Type 2
Determine the value of x for the given f(x) or vice versa and complete the tables. Plot and construct your linear function graph.
Is the Function Linear or Nonlinear | Table
Study the table to see if the rate of change in x and y values is constant to determine if it represents a linear function or not.
Evaluate each function from the graph for specific values of x, for given function rules, and find values of x that make f(x) = g(x).
