Functions, Domain and Range

Front

What is the domain? Options: x = 2, −∞ < x < ∞, y = 2, none of these

Back

−∞ < x < ∞

Front

What is the RANGE? Options: {-3, 3], all real numbers, [-4, 5], [-4, ∞)

Back

[-4, 5]

Front

What is the DOMAIN? Options: [0, ∞), (-∞, 0), All real numbers, {0, 1, 2, 3, 4,...}

Back

[0, ∞)

Front

What is the range of the function? Options: [-1, +∞), (-1,1), [1.5, +∞), (-2, 2)

Back

[-1, +∞)

Front

What is the range? Options: [-∞, +∞], [-2, 2], (-∞, ∞), [0, 2]

Back

[-2, 2]

Front

Does the graph represent a function? If you have an x value that has 2 "y" values it is NOT a function!

Back

No, because the vertical line test shows there are repeating input values

Front

Which graph does NOT pass the vertical line test? Options: Graph 1, Graph 2, Graph 3, Graph 4

Back

Graph 1

Front

Is the relation shown a function?

Back

No, because the x-value 11 is paired with 5 and 8.
