Function Notation Practice

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) = -2 mean?

Back

It means that when the input x is substituted into the function f, the output is -2.

Front

How do you find the value of a function at a specific point?

Back

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

Front

What is the output of h(x) = -9x + 5 when x = 8?

Back

h(8) = -67.

Front

What does it mean if f(____) = 214?

Back

It means that there is a specific input value that, when substituted into the function f, results in an output of 214.

Front

If f(x) = -4x - 5, what is f(1)?

Back

f(1) = -9.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function; if a vertical line intersects the graph at more than one point, it is not a 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.
