Domain Range and Identifying Functions (Unit 3)

Is this graph a function?

• Yes, because it passes the vertical line test.

• No, because it fails the vertical line test

Does this Mapping Diagram repersent a function?

• Function, because each input has exactly one output.

• Not a Function, because an input has two outputs.

Is this relation a Function?

• Yes, because it passes the vertical line test.

• No, because it fails the vertical line test.

CCSS.HSF.IF.A.2

Which choice describes the ranges of this graph.

• y>0

• y≤0

• y≥0

• All real numbers

• y≥1

Which choice describes the domain of this graph.

• x<0

• x≥0

• All Real Numbers

• x≥1

Is the relation a function? Why?

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
