Question 1
What is the second derivative of 
Explanation: To find the second derivative, first we need to find the first derivative.
To do that, we can use the power rule. To use the power rule, we lower the exponent on the variable and multiply by that exponent.
We're going to treat 
as 
since anything to the zero power is one.
Notice that 
since anything times zero is zero.
Just like it was mentioned earlier, anything to the zero power is one.
Now we repeat the process using 
as our expression.
Like before, anything times zero is zero.
Anything to the zero power is one.
as since anything to the zero power is one.
Notice that since anything times zero is zero.
Just like it was mentioned earlier, anything to the zero power is one.
Now we repeat the process using as our expression.
Like before, anything times zero is zero.
Anything to the zero power is one.
