The first function has a domain of all real numbers and a range of all real numbers greater than or equal to 3. The second function has a domain of all real numbers except for 0 and a range of all real numbers except for 1.
Function 1:
Domain: All real numbers. This means the function can accept any input value, from positive or negative infinity.
Range: All real numbers greater than or equal to 3. The function outputs values that are 3 or higher, but never less than 3.
Function 2:
Domain: All real numbers except for 0. The function cannot be evaluated when the input is 0, as it would result in division by zero, which is undefined.
Range: All real numbers except for 1. The function outputs all values except for 1, regardless of the positive or negative sign of the input.
