Algebra 1 Unit 2: Functions & Relations

What is the name of the flat grid formed by the intersection of the x-axis and the y-axis at the origin (0,0)?

In mathematics, a rule where every input has exactly one output is called a:

A visual tool, such as a(n) (a)   diagram, is used to show how input values are matched with output values using arrows drawn between 2 oblong shapes with lists of numbers

Which term describes a set of ordered pairs, such as {(1, 3), (2, 5), (3, 7)}?

Which test is used on a graph to determine if it represents a function by checking if any vertical line crosses the graph more than once?

If a data set includes all possible fractional values within an interval, such as measuring the exact temperature throughout the day. On this type of a graph there is a line connecting the values. The data is described as:

In a scenario where the total cost of a phone plan depends on the number of gigabytes of data used, which variable is the independent variable?

The set of all possible input values (x-values) for a function is known as the (a)   .

For the set of ordered pairs (1, 4), (2, 6), and (3, 8), what is the range?

To (a)   a function means to substitute a specific number for the variable and simplify the expression to find the result.
