Answer:
D.
Step-by-step explanation:

Did u ever get the answer
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}
Answer:
Fourth option
Step-by-step explanation:
When graphing the given inequalities you will get a region like the one shown in the attached image. This region is delimited by 4 straight

The points indicated at the ends of the region are the maximum possible values of x and y.
We must test these points in the objective function
and see which point maximizes the value of P.
<em><u>Remember that the boundaries of the region are not included.
</u></em>
We can prove the point <em>x = 0</em> and <em>y = 39</em> because (0,4) is not included in the region.

Now we test the point <em>x = 33</em> and <em>y = 16
</em>

Now we test the point <em>x = 44</em> and <em>y = 0</em>

Finally the optimal value is:
<em>x = 33 oz</em>
<em>y = 16 oz
</em>
