Function Notation

Front

What is function notation?

Back

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

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

Back

f(1) = 3

Front

If g(x) = 3x + 1, what is g(2)?

Back

g(2) = 7

Front

What does f(x) = x^2 + 7 represent?

Back

It represents a quadratic function where the output is the square of the input plus 7.

Front

If f(x) = 2x + 1, find f(4).

Back

f(4) = 9

Front

What is the output of a function?

Back

The output of a function is the value that results from applying the function to an input.

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.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation.

Front

What is the difference between linear and quadratic functions?

Back

Linear functions have a constant rate of change and are represented by a straight line, while quadratic functions have a variable rate of change and are represented by a parabola.
