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

What does f(x) represent?

Back

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

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 expression and simplify.

Front

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

Back

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

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 (f(x) values) that the function can produce.

Front

How do you find the x-value when f(x) is given?

Back

To find the x-value when f(x) is given, set the function equal to the given value and solve for x.

If h(a) = 3 - 2a, what is h(0)?

Back

h(0) = 3 - 2(0) = 3.

Front

What is a quadratic function?

Back

A quadratic function is a polynomial function of degree 2, typically written in the form f(x) = ax^2 + bx + c.

Front

If f(x) = x^2 - 4, what is f(-2)?

Back

f(-2) = (-2)^2 - 4 = 0.
