SOLUTION
From the question given, the cost of the toy truck is $36.50 before tax.
Now, the store selling the toy truck adds a 6% sales tax. This means

Now, we will add this $2.19 to the initial cost, we have

This gives $38.69.
Finally we will do a discount of 10%. 10% discount is

We will then subtract this 3.869 from 38.69, we get

That is 34.821. The 1 which is the last number at the decimal part is less than 5, so we ignore it and our answer becomes $34.82
We know that the graph of g(x) is the result of a shift of 2 units down from f(x).
Then, f(x) and g(x) are related by:

Taking the derivative:

This is because the derivative of a constant number is 0. Finally, evaluating at x = 2:
You have to add 4 and 9 then drop your variable
