Could someone please explain to me what the range and domain of a function is and how to find them? I just don't understand what they mean
Thank You
Thank You
Sure, why not?swatmedic05 said:But domain and range can't share a common number Can they?
They don't have to but they certainly can.swatmedic05 said:But domain and range can't share a common number Can they?
The domain of a function is the set of all possible input values for the function. In other words, it is the set of values that can be plugged into the function to obtain an output.
The range of a function is the set of all possible output values for the function. In other words, it is the set of values that the function can produce when given certain input values.
To determine the domain of a function, you must first look at any restrictions or limitations on the input values. These can be in the form of excluded values, such as dividing by zero, or restrictions on the type of numbers allowed. The range can be determined by looking at the output values the function can produce.
Yes, the domain and range of a function can be infinite. This occurs when there are no restrictions on the input or output values, and the function can take on any real number as its input or output.
Understanding the domain and range of a function is important because it helps us understand the behavior of the function and the limitations on its input and output values. It also allows us to identify any potential errors or issues with the function and make necessary adjustments.
