D. xb-a=y because it the close to being it it looks like
Answer:
Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.
Step-by-step explanation:
Answer:
The given function is
It's important to know that logarithms are the opposite function to exponentials, which means their domains and ranges are defined the opposite way.
The domain of logarithms is restricted, because negative numbers or the zero is not allowed in their domains. So, the domain of this function is:
On the other hand, its range is not restricted, so it's defined:
The image shows the graph of this function, there you can observe its domain and range set definitions.
