The term "domain" refers to the set of all possible input values for a function. If a function's domain is all real numbers, it means that you can input any real number into the function without encountering restrictions such as division by zero or taking the square root of a negative number. Examples of functions with this domain include linear functions and polynomial functions. However, specific functions may have restricted domains based on their mathematical characteristics.
Quadratic functions have a restricted domain because they can produce complex or undefined values for certain inputs, particularly when considering their roots or specific contexts, such as real-world scenarios where negative values may not be meaningful. In contrast, linear functions have a constant rate of change and are defined for all real numbers, allowing them to extend infinitely in both directions without encountering issues of undefined values. This inherent difference in their mathematical structure leads to the domain restrictions seen in quadratics.
The domain is the possible values that can be input into the function and produce a real number output.
The domain of the exponential parent function, typically represented as ( f(x) = a^x ) (where ( a > 0 )), is all real numbers, expressed as ( (-\infty, \infty) ). The range, on the other hand, consists of all positive real numbers, expressed as ( (0, \infty) ). This means the function never reaches zero or negative values, but can approach zero asymptotically.
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
Some functions are only defined for certain values of the argument. For example, the the logarithm is defined for positive values. The inverse function is defined for all non-zero numbers. Sometimes the range determines the domain. If you are restricted to the real numbers, then the domain of the square root function must be the non-negative real numbers. In this way, there are definitional domains and ranges. You can then chose any subset of the definitional domain to be your domain, and the images of all the values in the domain will be the range.
y = 1/x
There are no points of discontinuity for exponential functions since the domain of the general exponential function consists of all real values!

The domain is all real numbers, and the range is nonnegative real numbers (y ≥ 0).
Domain and range are used when you deal with functions - so basically you use them whenever you deal with functions.

The domain is any subset of the real numbers that you choose, The range is the set of all values that the points in the domain are mapped to.
Periodicity is not a characteristic.
The domain of a function represents the set of x values and the range represents the set of y values. Since y=x, the domain is the same as the range. In this case, they both are the set of all real numbers.
