FOM1 Function Notation Practice

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.

Front

How do you evaluate a function at a specific point?

Back

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

Front

What does f(0) represent in function notation?

Back

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

Front

If f(x) = -3(x-1), what is f(0)?

Back

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

Front

What is an ordered pair in the context of functions?

Back

An ordered pair is a pair of numbers (x, y) that represents a point on a graph, where 'x' is the input and 'y' is the output of the function.

Front

If f(2) = 4, how can this be expressed as an ordered pair?

Back

This can be expressed as the ordered pair (2, 4).

Front

What does it mean to find f(1)?

Back

Finding f(1) means to substitute 1 for x in the function and calculate the output.

Front

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

Back

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

Front

What does it mean to find f(3)?

Back

Finding f(3) means to substitute 3 for x in the function and calculate the output.

Front

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

Back

f(3) = 3^2 = 9.
