Evaluate With Function Notation

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

f(1) represents the output of the function f when the input is 1.

f(1) = 5.

f(-2) = 7.

To find x when f(x) = -2, solve the equation f(x) = -2.

f(3) = 20.

f(-2) = 1.

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

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

To evaluate a function means to calculate the output value for a given input value.
