Domain and Range Exponential Functions

Front

What is the definition of Domain in a function?

Back

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

Front

What is the definition of Range in a function?

Back

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

Front

What is the domain of the function f(x) = 15?

Back

All real numbers.

Front

What is the range of the function f(x) = 15?

Back

{15}.

Front

What is the domain of an exponential function?

Back

All real numbers.

Front

What is the range of an exponential function?

Back

y > 0.

Front

If a function has a range of y > 80, what does this imply about its outputs?

Back

The outputs of the function are all values greater than 80.

Front

What does it mean if a function's domain is restricted to 0 < x < 30?

Back

The function is only defined for x-values between 0 and 30, not including 0 and 30.

Front

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

Back

Identify the lowest and highest y-values that the graph reaches.

Front

What is the range of the function if its graph approaches but never touches the x-axis?

Back

y > 0.
