Acc Functions: Domain and Range 2024

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.

Front

How do you find the domain of a function from its graph?

Back

The domain can be found by identifying the x-values for which the graph has points.

Front

How do you find the range of a function from its graph?

Back

The range can be found by identifying the y-values that the graph reaches.

Front

What does it mean if a function is defined for all real numbers?

Back

It means the domain of the function includes every possible real number.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the highest or lowest point of the graph, depending on the direction it opens.

Front

What is the effect of a vertical shift on the graph of a function?

Back

A vertical shift moves the graph up or down without changing its shape.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the x-value into the function and simplify.

Front

What is a piecewise function?

Back

A piecewise function is a function defined by different expressions for different intervals of the domain.
