What test can you use to determine if a graph is a function?

• Slope Test

• Range Test

• Horizontal Line Test

• Vertical Line Test

If a vertical line intersects a graph more than once, what does it indicate?

• The graph has no range

• The graph is a function

• The graph is not a function

• The graph has no domain

For a graph that starts at x=3 and extends to the right indefinitely, what is the domain?

• x ≥ 3

• x > 3

• x ≤ 3

• x < 3

Why is a graph that extends indefinitely to the right and upwards considered a function?

• It has no x values

• It has multiple y values for each x value

• It passes the vertical line test

• It passes the horizontal line test

What is the domain of a graph that starts at x=3?

• x > 3

• x ≤ 3

• x < 3
