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 function name and x is the input variable.

Front

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

Back

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

Front

What does f(0) represent in function notation?

Back

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

Front

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

Back

f(2) = 2^2 = 4.

Front

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

Back

f(x) is equivalent to y in the context of functions, where y represents the output.

Front

How do you express the equation y = 3x + 5 in function notation?

Back

f(x) = 3x + 5.

Front

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

Back

f(1) = 4(1) - 1 = 3.

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(-1)?

Back

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

Front

What is the output of f(x) when f(x) = 5?

Back

The output is 5, but the input x can vary depending on the function.
