Find the domain of the function .

In summary, a domain in a function is the set of all possible input values for which the function is defined. To determine the domain, you need to consider any restrictions on the input values, such as type of numbers or variables. A function can have an empty domain if there are no possible input values that satisfy the restrictions, and it can have an infinite domain if there are no restrictions. It is important to determine the domain of a function to understand its behavior, identify any potential issues or limitations, and accurately graph the function and find its range.

Let f(A) = 0 and solve for A.

Do the same for 1 and 3.

What is the definition of a domain in a function?

A domain in a function is the set of all possible input values for which the function is defined. It is also known as the independent variable or the x-values.

How do you determine the domain of a function?

To determine the domain of a function, you need to look at the restrictions on the input values. This can include restrictions on the type of numbers (such as real numbers or integers) or restrictions on the variables (such as avoiding division by zero or taking the square root of negative numbers).

Can a function have an empty domain?

Yes, a function can have an empty domain if there are no possible input values that satisfy the restrictions. For example, the function f(x) = 1/x has an empty domain because dividing by zero is undefined.

Is it possible for a function to have an infinite domain?

Yes, a function can have an infinite domain if there are no restrictions on the input values. For example, the function f(x) = x has an infinite domain because any real number can be an input value.

Why is it important to determine the domain of a function?

Determining the domain of a function is important because it helps us understand the behavior of the function and identify any potential issues or limitations. It also allows us to accurately graph the function and find its range, which is the set of all possible output values.
