) what do you get when you do as you propose ?[-2,10] if i sub this values into f(2x+4) i would get 0 and 24 does this mean that the domain would be (0,24)BvU said:Don't ask. Do it: that counts as an attempt at solution. Ask when stuck...
Or (in a friendlier manner
the domain is pairs of x coordinates in order and the range is pairs of y coordinates in orderfresh_42 said:
The domain of a function is the set of values which are allowed to be used as inputs to the function. The notation "[-2,10]" denotes a range of values from -2 up through 10, inclusive. It does not denote an ordered pair.Mark53 said:
A domain refers to the set of all possible input values of a function, while a range refers to the set of all possible output values of a function.
To find the domain of a function, you can look at the given input values or find any restrictions on the input values. To find the range, you can analyze the behavior of the function and determine the output values it can produce.
Yes, it is possible for the domain and range of a function to be the same. This can happen when the function is a one-to-one function, meaning each input value corresponds to a unique output value.
If the domain or range of a function is not specified, it is assumed to be all real numbers. However, it is important to check for any restrictions or limitations on the input or output values.
Knowing the domain and range of a function helps us understand the behavior and limitations of the function. It also allows us to determine the possible values the function can take and helps us identify any potential errors or issues with the function.
