Q1. The limit from the right is -4. (The limit from the left, and the value of f(3) are different, but that doesn't matter for the question asked. Taken together, they mean that the limit as x approaches 3 does not exist. But that is not the question asked.)
Q2. f(x) = 4/x.
f'(x) = -4/x^2, so f'(2) = -4/2^2 = -1.
Q3. Since the denominator is zero at x=7, the only answer choice that makes any sense is the first one:
-∞; x = 7
It also happens to be the right one.
Answer:
the cost of each cookie is
the cost of each muffin is
Step-by-step explanation:
Let
x-----> the cost of each cookie
y----> the cost of each muffin
we know that
-----> equation A
-----> equation B
Using a graphing tool
The solution of the system of equations is the intersection point both graphs
The intersection point is
see the attached figure
therefore
the cost of each cookie is
the cost of each muffin is
