Function Notation

Front

What is function notation?

Back

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

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the value of the input variable into the function's equation.

Front

If f(x) = 2x + 1, what is f(1)?

Back

f(1) = 2(1) + 1 = 3.

Front

What does f(2) = 4 mean?

Back

It means that when the input to the function f is 2, the output is 4.

Front

How can you express the ordered pair for f(2) = 4?

Back

You can express it as (2, 4).

Front

What is the first step to evaluate f(x) = -3(x-1) at x = 0?

Back

Plug 0 into the function: f(0) = -3(0-1) = 3.

Front

If f(x) = x^2, what is f(3)?

Back

f(3) = 3^2 = 9.

Front

What is the output of the function f(x) = 2x - 5 when x = 4?

Back

f(4) = 2(4) - 5 = 3.

Front

How do you write the function value f(3) = 4 in ordered pair form?

Back

(3, 4) is the ordered pair.

Front

What is the significance of the variable 'x' in function notation?

Back

The variable 'x' represents the input value for which the function is evaluated.
