What is the domain of a function?

Back

The domain is the set of all possible input values (x-values) for a function.

Front

What is the range of a function?

Back

The range is the set of all possible output values (y-values) for a function.

Front

Does this mapping diagram represent a function? (Options: No, because there are repeating input values; Yes, because there are no repeating input values)

Back

Yes, because there are no repeating input values.

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range. (Options: D: {1, -3, -4,} R: {0, 1, 2, -4}, D: {-4, 0, 1, 2} R: {-4, -3, 1}, D: {0, 1, 2, 3, 4} R: {1, -3, -4}, D: {0, 1, 2, -4} R: {1, -3, -4, 1})

Back

D: {-4, 0, 1, 2} R: {-4, -3, 1}.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a curve is a function by checking if any vertical line intersects the curve at more than one point.

Front

What does it mean for a function to be one-to-one?

Back

A function is one-to-one if each output value is paired with exactly one input value, meaning no two different inputs produce the same output.
