Function Notation

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the letter 'f' followed by parentheses containing the input variable, such as f(x).

Front

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

Back

f(1) = 3

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

If f(x) = x^2, what is f(0)?

Back

f(0) = 0

Front

How do you find the value of a function at a specific point?

Back

To find the value of a function at a specific point, substitute the input value into the function's equation.

Front

What does it mean if a function is defined for x in the interval (-4, 4)?

Back

It means that the function has valid output values for all x-values between -4 and 4, not including -4 and 4.

Front

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

Back

f(2) = 4

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

If the domain of a function is [-2, 2], what does this indicate?

Back

It indicates that the function is defined for all x-values from -2 to 2, including -2 and 2.

Front

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

Back

f(-3) = 2
