If f(x) = 2x + 1, find f(1).

Back

f(1) = 3

Front

How would you write y = 2x - 3 in function notation?

Back

f(x) = 2x - 3

Front

Evaluate f(-2) if f(x) = x + 3.

Back

f(-2) = 1

Front

If a question asks you to find f(2), what does that mean?

Back

Let x = 2

Front

What is function notation?

Back

A way to represent a function using symbols, typically f(x), where f is the function name and x is the input.

Front

What does f(x) represent?

Back

f(x) represents the output of the function f for a given input x.

Front

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

Back

f(3) = 9

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The set of all possible output values (y-values) for the function.
