Learn the basics of how to determine the domain and range of a function

The video tutorial explains the concepts of domain and range using examples of coordinate points and graphs. It highlights the difference between listing points and understanding graphs, emphasizing that graphs represent infinite points. The tutorial guides viewers through identifying domain and range by analyzing which values are included or excluded, and concludes with a summary of these concepts.

What is the domain of the given points: (1,1), (-1,3), and (0,-2)?

• 1, 0, -1

• -1, 0, 1

• 0, 1, 2

• -2, 3, 1

When determining the domain from a graph, why is it impractical to list all points?

• Because there are infinitely many points on a line.

• Because graphs only have a few points.

• Because graphs do not have X values.

• Because graphs are always finite.

How does the domain of a graph extend?

• From one to ten.

• From zero to negative infinity.

• From negative infinity to positive infinity.

• From zero to positive infinity.

What is the lowest Y value in the range of the graph discussed?

• Three

• Two

• One

• Zero

What is the highest Y value that the graph can reach?

• Zero

• Infinity

• Five

• Ten
