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.

Front

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

Back

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

Front

What does f(x) represent in a function?

Back

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

Front

How do you find f(a) for a function f(x)?

Back

To find f(a), substitute 'a' into the function in place of 'x' and simplify.

Front

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

Back

f(-3) = (-3)^2 = 9.

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

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

Front

If f(x) = 3x - 4, what is f(0)?

Back

f(0) = 3(0) - 4 = -4.

Front

What is the difference between f(x) and g(x)?

Back

f(x) and g(x) can represent different functions, each with its own rule for output based on input.

Front

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

Back

f(5) = -5 + 5 = 0.
