The parent graph of the absolute function is translated 4 units to the left and 2 units up to create a new graph. Write an equation to represent the new graph.

• The domain is {-3, 2, 4}.

• The range is {-3, -2, 0, 1}.

• The relation is a function.

• The relation is not a function.

Given f(x) = 3x² – 3x + 5.3, find f(3b).

• 9b² – 3b + 5.3

• 9b² – 9b + 5.3

• 27b2 – 3b + 5.3

• 27b² – 9b + 5.3

The table below shows the number of students in Mrs. Lewis’ class who have birthdays in each month, which is represented by a number. Identify the domain and range. Determine whether the relation is discrete or continuous and whether it represents a function.

• D = {1, 2, 3, …, 10, 11, 12}; R = {0, 1, 2, 3, 4, 5, 8}; continuous; function

• D = {1, 2, 3, …, 10, 11, 12}; R = {0, 1, 2, 3, 4, 5, 8}; discrete; function

• D = {all real numbers}; R = {all real numbers}; continuous; function

• D = {all real numbers}; R = {all real numbers}; discrete; function

Find the x- and y-intercepts of the graph of x² – x – 6 = 0, which is shown below.

• x-intercept: –6; y-intercepts: –3, 3

• x-intercept: –6; y-intercepts: –2, 3

• x-intercepts: –3, 3; y-intercept: –6

• x-intercepts: –2, 3; y-intercept: –6
