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.

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

Back

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

Front

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

Back

f(3) = 2(3) + 1 = 7.

Front

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

Back

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

Front

If f(x) = 2x + 1, what is f(4)?

Back

f(4) = 2(4) + 1 = 9.

Front

What does f(x) represent?

Back

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

Front

In function notation, what does 'f' typically represent?

Back

In function notation, 'f' typically represents the name of the function.

Front

What is the output of a function when the input is 0, if f(x) = 3x + 2?

Back

f(0) = 3(0) + 2 = 2.

Front

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

Back

f(5) = 5^2 = 25.

Front

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

Back

f(3) = 3 - 3 = 0.
