How do you find the domain and range of an equation?
Since this is not my area of expertise, I searched Google under the key words "domain range equation" to get these possible sources:

I hope this helps. Thanks for asking.
To find the domain and range of an equation, you need to understand the concept of domain and range in mathematics.
The domain of a function is the set of all possible input values for which the function is defined. In simpler terms, it represents the x-values that the function can take.
To find the domain of an equation, you need to understand any restrictions on the variable in the equation. For example, if the equation involves a square root, then the radicand (the expression inside the square root) must be greater than or equal to zero, so you need to set that inequality and solve for the variable.
The range of a function is the set of all possible output values that the function can produce. In simpler terms, it represents the y-values that the function can take.
To find the range of an equation, you need to analyze the behavior of the equation as the input values vary. For example, if the equation represents a quadratic function, you can use the concept of vertex and the shape of the parabola to determine the possible range.
In some cases, it may be helpful to graph the equation or use specific mathematical tools or techniques to determine the domain and range.
I hope this explanation helps you understand how to find the domain and range of an equation.
