Function Notations Practice

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the format f(x), where 'f' is the name of the function and 'x' is the input variable.

Front

What does f(x) = 5 mean?

Back

It means that the output of the function f for the input x is equal to 5.

Front

How do you find the value of x when f(x) = k?

Back

To find x when f(x) = k, set the function equal to k and solve for x.

Front

What are inputs in a function?

Back

Inputs are the values that are fed into a function, typically represented by the variable x.

Front

What is the output of a function?

Back

The output is the result of applying the function to an input, often represented as f(x).

Front

What is the range of a function?

Back

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

Front

What does it mean if a function is linear?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the x-intercept of a function?

Back

To find the x-intercept, set f(x) = 0 and solve for x.

Front

What is the slope of a linear function?

Back

The slope of a linear function indicates the steepness of the line and is calculated as the change in y over the change in x (rise/run).

Front

What does f(5) = 3 mean?

Back

It means that when the input x is 5, the output of the function f is 3.
