What are we learning about in Algebra 2 class right now?

• Types of lines

• Types of graphs

• Functions and inverse functions

• Types of angles

Is the following a function? Explain.

• Yes, because it passes the vertical line test.

• Yes, because each input is mapped to exactly 1 output.

• No, because it fails the vertical line test.

• No, because the lines do not go straight across.

Is the following a function? Explain.

• Yes, because each input is mapped to exactly one output.

• Yes, because it passes the vertical line test.

• No, because it fails the vertical line test.

• No, because each input does not map to exactly one output.

Is the following a function? Explain.

• Yes, because it is on a graph.

• Yes, because it passes the vertical line test.

• No, because it fails the vertical line test.

• No, because it is a curved graph.
