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 express the equation y = 2x - 3 in function notation?

Back

f(x) = 2x - 3

Front

What does f(1) represent?

Back

f(1) represents the output of the function f when the input x is 1.

Front

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

Back

f(-2) = 1

Front

If f(x) = 2x + 1, what is f(3)?

Back

f(3) = 7

Front

What is the output of f(x) = x^2 when x = 4?

Back

f(4) = 16

Front

What is the relationship between f(x) and y?

Back

f(x) is the same as y; both represent the output of a function.

Front

If f(x) = 3x - 5, what is f(0)?

Back

f(0) = -5

Front

What does it mean to evaluate a function?

Back

To evaluate a function means to find the output value for a given input.

Front

If f(x) = x + 2, what is f(5)?

Back

f(5) = 7
