Function Notation Practice

Front

What is function notation?

Back

Function notation is a way to represent functions in mathematics, typically written as f(x), where 'f' is the name of the function and 'x' is the input variable.

Front

What does f(6) represent in function notation?

Back

f(6) represents the output of the function f when the input is 6.

Front

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

Back

To find the y-intercept of a function, set x to 0 and solve for y.

Front

What is the y-intercept of the function f(x) = x^2 - 3 + 2x?

Back

The y-intercept is (0, -3).

Front

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) is associated with exactly one output (y-value).

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the value of the input variable into the function and simplify.

Front

What is the output of f(x) = x^2 - 3 + 2x when x = 6?

Back

The output is 45.

Front

What does it mean if a relation is 'not a function'?

Back

It means that at least one input is associated with more than one output.

Front

How do you read f(x)?

Back

It is read as 'f of x'.

Front

What is the significance of the graph in evaluating functions?

Back

The graph visually represents the function, allowing you to find outputs for given inputs.
