For this case we have the following expression:
We substitute a small number h, that is,
So:
It is observed that the value of the expression is very large, that is, it increases with small values of h
We substitute a large number h, that is,
So:
It is observed that the value of the expression decreases.
Answer:
The value of the given expression decreases when h increases from a small positive number to a large positive number.
This is equal to:
When you add a negative number, it turns into subtraction.
First, I would change it to mixed numbers:
Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:
Now, you simply subtract:
10-9=1
1/4 is your answer.
I hope this helps :)
