Answer:
Option a.

Step-by-step explanation:
You have the following limit:

The method of direct substitution consists of substituting the value of
in the function and simplifying the expression obtained.
We then use this method to solve the limit by doing 
Therefore:


By definition, any number raised to exponent 0 is equal to 1
So


Finally

This is a change in both supply and demand. Due to farmers raising fewer cows the supply of cows goes down. Because there is more of a need of cows due to the shortage the demand or need for them goes up. Due to the limited amount of cows and the high demand prices will go up.
About 3 gallons of blue paint will be needed because if you add 175+175 it equals 350 and then add another 175 it equals 525.
6 - 3 = 3
-2 - (-9) = 7
(3 , 7)
