Front

What does f(x) represent in a function?

Back

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

Front

How do you read f(x)?

Back

f of x.

Front

If f(x) = x - 5, what is the value of x when f(x) = 15?

Back

x = 20.

Front

If f(x) = 19, what is the value of x?

Back

x = 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

What does the notation [a, b) mean in terms of intervals?

Back

It means that the interval includes 'a' but does not include 'b'.

Front

If f(x) = 3, what is the value of x?

Back

x = 6.

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

How do you find the value of x in a linear equation?

Back

Isolate x on one side of the equation.

Front

What is the difference between an open interval and a closed interval?

Back

An open interval (a, b) does not include the endpoints a and b, while a closed interval [a, b] includes both endpoints.
