Let
x-------> the number of hours
y------> the temperature in degrees Fahrenheit
we know that
For 
For 
The domain of the function is the interval----------> ![[0,30]](https://tex.z-dn.net/?f=%5B0%2C30%5D)
The range of the function is the interval----------> ![[-10,30]](https://tex.z-dn.net/?f=%5B-10%2C30%5D)
therefore
<u>the answer is</u>
The domain is all real numbers 0 through 30
If human development really does proceed continuously, what value does stage theories of development have?
Answer:
Even if human development is continuous, there is some value in stage theories of development. A stage theory of development allows experts to examine the developmental progress of individuals and establish a basis for developmental changes. This can help identify developmental issues earlier. Stage theories can also help researchers who are examining physical development examine discrete changes in the brain that allow certain developmental milestones to be reached. Finally, stage theories can give one a sense of where an individual is developmentally, and can prepare the person for changes that may occur during their lifetime.
