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 based on its domain.

Front

Back

The range is @@(- ext{∞}, 6]@@.

Front

How do you determine the range of a function?

Back

To determine the range, analyze the output values of the function based on its formula and any restrictions from the domain.

Front

Back

It means that y is greater than or equal to 3 and can go up to infinity.

Front

What is the domain of a function?

Back

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

Front

Back

The domain is all real numbers, denoted as {x | x = all real numbers}.

Front

What is an absolute value function?

Back

An absolute value function is a function that outputs the distance of a number from zero, always resulting in a non-negative value.

Front

What is the solution to the equation |v + 8| - 5 = 2?

Back

The solutions are v = -1 and v = -15.

Front

Back

It means x can take any value from -2 to 4, inclusive.

Front

What is the effect of a negative sign in front of an absolute value function?

Back

A negative sign in front of an absolute value function reflects the graph across the x-axis.
