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 evaluate a function at a specific point?

Back

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

Front

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

Back

f(2) = 2(2) + 1 = 5.

Front

What does f(0) represent in function notation?

Back

f(0) represents the value of the function when the input x is 0.

Front

If f(x) = -3(x-1), find f(0).

Back

f(0) = -3(0-1) = 3.

Front

What is the output of f(1) if f(x) = 2x + 1?

Back

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

Front

How do you find x if f(x) = -2?

Back

Set the function equal to -2 and solve for x.

Front

If f(x) = 2x + 1, what is the first step to find f(1)?

Back

Plug a 1 in for all the x's.

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 (f(x) values) that the function can produce.
