Unit 4 - Functions

Which of the following words do not belong? Dependent Variables Range Output x-values What is the domain of this set? {(2,5), (4,7), (3,6), (6,9)} {5, 6, 7, 9} {2, 3, 4, 6} {2, 3, 4, 5, 6, 7 9} {(2,5), (4,7), (3,6), (6,9)} What is the range of this set? {(2,5), (4,7), (3,6), (6,9)} {5, 6, 7, 9} {2, 3, 4, 6} {2, 3, 4, 5, 6, 7 9} {(2,5), (4,7), (3,6), (6,9)} What is a relationship between sets of information? Domain Range Relation Function Which of the following words does not belong? Domain Dependent Variable Input x-values What is a relation in which each input has only one output? Input Output Function Relation Is the following relation a function? Yes No If a vertical line passes through a graph more than once, the graph does NOT represent a function. True False Determine if the graph is a function. Function Not a Function What is used to determine whether or not a graphrepresents a function? x-axis and y-axis Straight/Curved Line Vertical Line Test Horizontal Line Test For , find the range value the domain value is 5. For , find the domain value when the range is 17.Determine if the graph is a function. Not a Function Function Given the inputs of {-3, 0, 3, 6}, name the domain and range of the function: (Separate numbers with commas, but no spaces) Domain: { } Range: { } For the function graphed below, determine the output value when the input value is 1. David measures how many inches his tomato plant grows every week. What is the dependent variable? Inches the plant has grown The number of weeks it has been growing What is the independent variable? Your math grade reflects the number of assignmentsyou have turned in. Math grade Assignments turned in Cell phone bill, because it is the dependent variable Cell phone bill, because it is the independent variable Minutes used, because it is the dependent variable Minutes used, because it is the independent variable The minutes used each much determines your cell phone bill. If this relationship was graphed, which variable would be graphed on the x-axis? |
