Answer:
1. (f+g)(x) = 2x^2 +4x +2
2. (f -g)(x) = -2x^2 +4x -4
5. (f+g)(x) = x^2 +2x -1
6. (g -f)(x) = x^2 -2x -1
Step-by-step explanation:
None of these are compositions. They are only sums or differences.
(f±g)(x) = f(x) ± g(x)
__
1. (f+g)(x) = f(x) +g(x) = (4x -1) +(2x^2 +3)
(f+g)(x) = 2x^2 +4x +2
__
2. (f -g)(x) = f(x) -g(x) = (4x -1) -(2x^2 +3)
(f -g)(x) = -2x^2 +4x -4
__
5. (f +g)(x) = f(x) +g(x) = (2x) +(x^2 -1)
(f+g)(x) = x^2 +2x -1
__
6. (g -f)(x) = g(x) -f(x) = (x^2 -1) -(2x)
(g -f)(x) = x^2 -2x -1
The factored form of the related polynomial is (x - 1)(x - 9)
<h3>How to determine the
factored form of the related polynomial?</h3>
In this question, the given parameter is the attached graph
From the graph, we can see that the curve crosses the x-axis at two different points
These points are the zeros of the polynomial function.
From the graph, the points are
x = 1 and x = 9
Set these points to 0
x - 1 = 0 and x - 9 = 0
Multiply the above equations
(x - 1)(x - 9) = 0
Remove the equation
(x - 1)(x - 9)
Hence, the factored form of the related polynomial is (x - 1)(x - 9)

Answer:
<u>The patient is going to drink 14 pints of medicine over a week</u>
Step-by-step explanation:
1. Let's review all the information provided to answer the question correctly:
Amount of medicine the doctor told his patient to drink over a week = 3 1/2 cups
1 full cup = 4 pints
2. How much is the patient going to drink over the week?
For answering this question, we multiply this way:
3 1/2 = 3.5
3.5 * 4 = 14
<u>The patient is going to drink 14 pints of medicine over a week</u>
