Interpreting Domain and Range

Jenny says that this mapping diagram DOES NOT represent a function because the inputs of -1, 1 and, 0 share an output of 0.

Explain why you agree or disagree with Jenny.

The graph shows the height (cm) of a candle as it burns, what is the y intercept and what does the y-intercept mean?

• b=9, Candle starts at 9 cm.

• b=9, the candle burns 9 inches per hour.

• b=2, the candle burns 2 inches per hour.

• b = 5, The candle ends at 5 cm

Which relation does the mapping show?

• <(p>{(0, 1), (1, 2),(3, 4)}

• {(1, 0), (2, 1), (2, 2), (4, 3)}

• {(0, 1), (1, 2), (2, 2), (3, 4)}

• {(1, 0), (2, 1), (4, 3)}

What is the range of the table?

• <-4, 0, 1, 3>

• <-2, 0, 2, 3>

• <-4, -2, 0, 1, 2, 3>

• < (0, 0), (2, -4), (3, 3), (-2, 1) >

Is the relation shown in the mapping a function?

• No, because -1 and 4 are pared with 4.

• Yes, because every input is paired with exactly one output.
