It's "all values except 4". 4 is a vertical asymptote and the function does not exist there at all. But the left side comes in from negative infinity and goes down to negative infinity, and on the right it comes down from positive infinity, but since it's getting closer and closer to the horizontal asymptote of y = 0, it's decreasing there too.
In its simplest form the domain is all the values that go into a function, and a range is all the values that come out.
Answer: Rate of change is used to mathematically describe the percentage change in value over a defined period of time, and it represents the momentum of a variable. ... Subtract one and multiply the resulting number by 100 to give it a percentage representation.

We need to find the angle of elevation of the sun from the ground. Let the angle be θ. We can use trigonometry to find it. So,
So, the required angle of elevation of the sun is equal to 
.
