2. Independent vs. Dependent Variables
Independent Variable: A variable in a functional relation whose value determines the value or values of other variables.
Dependent Variable: a variable in a functional relation whose value is determined by the values assumed by other variables in the relation.
Define each word in your own terms

3. Domain vs. Range
Domain: the set of "input" or argument values for which the function is defined
Range: the codomain or the image of the function, depending upon usage

4. Representation

5. Increasing vs. Decreasing function
Increasing function: The y-value increases as the x-value increases.
Decreasing function: The y-value decreases as the x-value increases

6. Increasing vs. Strictly Increasing

8. Function vs. Relation
Function:  A function is a set of ordered pairs in which each x-element has only ONE y-element associated with it.

9. Continuous vs. Discrete
Continuous: A function for which small changes in the input result in small changes in the output, a graph is a single unbroken curve.
Discrete: A function that is defined only for a set of numbers that can be listed
