Function Notations Practice

Front

What is function notation?

Back

Function notation is a way to represent a function using symbols. It typically uses the format f(x), where 'f' is the name of the function and 'x' is the input variable.

Front

If f(x) = -5x + 10, what is f(3)?

Back

f(3) = -5(3) + 10 = -15 + 10 = -5.

Front

What are the inputs of a function called?

Back

The inputs of a function are called 'domain' or 'inputs'.

Front

Given f(x) = 2x + 1, find f(1).

Back

f(1) = 2(1) + 1 = 2 + 1 = 3.

Front

What does the graph of a function represent?

Back

The graph of a function represents the relationship between the input values (x-axis) and the output values (y-axis).

Front

If f(x) = 5, how do you find x?

Back

To find x, you need to solve the equation f(x) = 5 for x.

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

If f(x) = 3, what does this mean?

Back

This means that when the input x is such that f(x) equals 3, the output is 3.

Front

What is the difference between inputs and outputs in a function?

Back

Inputs are the values you put into a function (x-values), while outputs are the values you get out of the function (y-values).

Front

How do you evaluate a function at a specific point?

Back

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