2.1 Function Notation Quick Check

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

What does the domain of a function represent?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What does the range of a function represent?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

In the function y = 0.15x + 1.5, what does 'x' represent?

Back

'x' represents the total ounces of yogurt purchased.

Front

What is the significance of the minimum and maximum values in a function's domain?

Back

The minimum and maximum values define the limits of the input values that can be used in the function.

Front

If f(x) = x - 5, what is the output when x = 10?

Back

f(10) = 10 - 5 = 5.

Front

What is a reasonable input value for a function?

Back

A reasonable input value is one that falls within the defined domain of the function.

Front

What type of numbers make up the domain in the function y = 0.15x + 1.5 for 10 ≤ x ≤ 14?

Back

All real numbers greater than or equal to 10 and less than or equal to 14.

Front

What is the output of the function y = 0.75x when x = 4?

Back

y = 0.75 * 4 = 3.

Front

What does it mean if a function's output is limited to a specific range?

Back

It means that the function can only produce certain values as outputs, which are defined by the range.
