Answer:
As you can see, the difference between the reciprocal of
and the inverse of
is that
and
.
Step-by-step explanation:
First lets find both the reciprocal of
and the inverse of
Recall that the reciprocal of a value is where you take a fraction and swap the places of the terms. In the case of
, 1 is the denominator, so

To find the inverse of a function, you first need swap the locations of x and y in the equation

Now, you need to solve for y

Now, lets rewrite each of these to better compare them

As you can see, the difference between the reciprocal of
and the inverse of
Answer:
about $1.17 for each soda
Step-by-step explanation:
Answer:
(a) 
(b) Domain:
<em>(See attachment for graph)</em>
(c) 
Step-by-step explanation:
Given



Solving (a): A function; l in terms of w
All we need to do is make l the subject in 
Divide through by 2

Subtract w from both sides


Reorder

Solving (b): The graph
In (a), we have:

Since l and w are the dimensions of the fence, they can't be less than 1
So, the domain of the function can be

Solving (c): Write l as a function 
In (a), we have:

Writing l as a function, we have:

Substitute
for l in 
becomes
