How do you find the domain and range of a function

What is the domain of a graph if the smallest X value is 1 and the largest X value is 6, with an open circle at 6?

• X is greater than 1 and less than 6

• X is between 1 and 6, inclusive

• X is greater than 1 and less than or equal to 6

• X is greater than or equal to 1 and less than 6

If a graph has a Y value range from -3 to 4, with an open circle at -3, what is the correct range?

• Y is between -3 and 4, inclusive

• Y is greater than -3 and less than or equal to 4

• Y is greater than or equal to -3 and less than 4

• Y is greater than -3 and less than 4

What does the vertical line test determine about a graph?

• If the graph is a function

• If the graph is symmetrical

• If the graph has a maximum point

• If the graph is continuous

In the vertical line test, what indicates that a graph is not a function?

• The line is parallel to the X-axis

• The line intersects the graph at exactly one point

• The line does not intersect the graph

• The line intersects the graph at more than one point

How is the domain defined for a graph that extends infinitely in both directions?

• From negative infinity to positive infinity

• From zero to one

• From zero to positive infinity

• From negative infinity to zero

What is the range of a graph that extends infinitely upwards but starts at Y=0?

• Y is greater than 0 and less than or equal to 10

• Y is less than or equal to 0

• Y is greater than or equal to 0 and less than infinity

• Y is between 0 and 10

What does an arrow on a graph indicate about its domain or range?

• The graph is finite

• The graph extends to infinity

• The graph is a function

• The graph has a maximum value
