What is the definition of a domain in mathematics?

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 definition of a range in mathematics?

Back

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

How do you find the domain of a rational function?

Back

To find the domain of a rational function, identify values that make the denominator zero and exclude them from the set of real numbers.

Front

Back

The domain is all real numbers except x = 2, or in interval notation: (-∞, 2) U (2, ∞).

Front

Back

The domain is all real numbers except x = -2 and x = 2, or in interval notation: (-∞, -2) U (-2, 2) U (2, ∞).

Front

Back

The range is all non-negative real numbers, or in interval notation: [0, ∞).

Front

Back

The range is all real numbers except 0, or in interval notation: (-∞, 0) U (0, ∞).

Front

How do you determine the range of a logarithmic function?

Back

The range of a logarithmic function is all real numbers, as it can take any value from negative to positive infinity.

Back

The domain is all real numbers greater than 3, or in interval notation: (3, ∞).

Back

The domain is all real numbers greater than 0, or in interval notation: (0, ∞).
