AFDA Unit 9 Test Review

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output for each input from a given set.

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 f(-4) for a given function?

Back

To find f(-4), substitute -4 into the function in place of x and simplify.

Front

How do you find f(3) for a given function?

Back

To find f(3), substitute 3 into the function in place of x and simplify.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as x increases, the value of f(x) also increases.

Front

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as x increases, the value of f(x) decreases.

Front

What is a graph of a function?

Back

A graph of a function is a visual representation of the relationship between the input values (x) and the output values (f(x)).

Front

What is the significance of the y-intercept in a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, indicating the output value when x=0.

Front

What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line, typically in the form f(x) = mx + b.
