What is the definition of a function?

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

How do you determine the domain of a linear function?

Back

For a linear function, the domain is typically all real numbers unless specified otherwise by constraints.

Front

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph.

Front

What does it mean for a function to have a zero?

Back

A zero of a function is a value of x for which the function's output (y-value) is zero.

Front

What is a y-intercept?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, represented by the coordinates (0, y).

Front

How do you find the range of a function given its domain?

Back

To find the range, evaluate the function for all values in the domain and determine the resulting output values.

Front

What is the significance of the graph of a quadratic function?

Back

The graph of a quadratic function is a parabola, which can open upwards or downwards, indicating the nature of the function's outputs.

Front

Back

It indicates that the function is defined for all x-values greater than -4.
