What is the definition of 'Range' in mathematics?

Back

The range of a function is the set of all possible output values (y-values) that result from using the function.

Front

Back

This notation describes the range of y, indicating that y can take any value from -3 to 5, inclusive.

Front

How do you find the range of a function?

Back

To find the range, identify all possible output values (y-values) for the given input values (x-values) of the function.

Simplify the expression: -8b + 3b + b

Back

-4b

Front

What is the definition of 'Domain' in mathematics?

Back

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

Front

Back

This notation describes the domain of x, indicating that x can take any value from -6 to 6, inclusive.

Front

Which of the following expressions is not equivalent to the others: 2(x - 4), 2x - 8, -8 + 2x, or 2 + x - 4?

Back

2 + x - 4 is not equivalent to the others.

Front

What is the range of the function if the output is defined as y > 0?

Back

The range is all positive real numbers, meaning y can take any value greater than 0.

Front

What does it mean to 'combine like terms' in algebra?

Back

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power.

Front

Back

This indicates that the output values (y-values) of the function can range from 0 to 6, inclusive.
