Applying the differentiation rule, it can be obtained that:
,
and
.
The exponential function exists a mathematical function designated by f(x)=\exp or e^{x}. Unless otherwise determined, the term generally directs to the positive-valued function of a real variable, although it can be extended to complex numerals or generalized to other mathematical objects like matrices or Lie algebras.
In mathematics, the derivative of a function of a real variable estimates the sensitivity to change of the function value affecting a change in its statement. Derivatives exist as a fundamental tool of calculus.
.
Given that .
So, differentiating with respect to
, we get:
.
So, using the above formula , we get:
.
Now, substituting in
and
, we obtain:
and
.
Therefore, applying the differentiation rule, we get:
,
and
.

Answer:
A. B. 25% discount
Step-by-step explanation:
PART A:
For the shirt:
Sale price of the shirt=$18
Cost of the shirt=$24
Now,
⇒
For the pair of shoes:
Sale price of the pair of shoes=$42
Cost of the pair of shoes=$56
Now,
⇒
So, the equation that represents the sale price y of an item that costs x dollars is:
PART B:
y=Sale price of an item
x=Cost of the item
Discount on the item
Percentage discount on the item×100
%
