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.

How do you evaluate a function at a specific value?

Back

To evaluate a function at a specific value, substitute the value into the function's equation in place of the variable.

If f(x) = 10x - 100, what is f(10)?

Back

f(10) = 0.

Front

How do you express the equation y = 2x - 3 in function notation?

Back

f(x) = 2x - 3.

Front

What does it mean to find x when f(x) = 2?

Back

It means to find the value of x that makes the function equal to 2.

Front

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

Back

f(1) = 3.

Front

Given f(x) = 3x - 7, if f(x) = 14, what is x?

Back

x = 7.

Front

What is the output of a function?

Back

The output of a function is the value that results from substituting an input into the function.

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

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.
