Read each question carefully and provide your best answer. Show your work where applicable.
1. A is a relationship between an input and an output.
2. In a mapping, for every input, there is exactly one .
3. The set of all possible input values is called the .
4. The set of all possible output values is called the .
5. Which of the following mappings represents a function?
{ (1, 2), (1, 3), (2, 4) }
{ (1, 2), (2, 3), (3, 4) }
{ (1, 2), (2, 2), (2, 3) }
{ (1, 2), (3, 2), (1, 4) }
6. In the mapping {(0, 5), (1, 6), (2, 7)}, what is the range?
{0, 1, 2}
{5, 6, 7}
{0, 1, 2, 5, 6, 7}
None of the above
7. For the mapping {(1, 3), (2, 4), (3, 5)}, describe the rule that transforms the input to the output.
8. If the rule is 'add 5 to the input', what is the output for an input of 7?
9. Plot the following points on the coordinate plane: (2, 3), (-1, 4), (0, -2).
10. Consider the mapping where the output is double the input. If the inputs are 1, 2, and 3, what are the corresponding outputs? Plot these points on a coordinate plane.
