Answer:
In the first one, 4 is multiplied by c. In the second one, 1/4 is multiplied by c.
Step-by-step explanation:
It means that The bicyclist rides 64 miles in 4 hours!! :)
First, is to raise the price to earn profit. Second, is to maintain the price to maintain the number of buyers. Third, is to maintain the price but to lessen the chicken feed inside a bag. Fourth, to tell the customers first that you will raise the price of your product.
I am assuming that you mean

and

Now, let's look for common factors. The first one is

After we take that out, we are left with 14 and 22. We can take a 2 out of both of these, so the greatest common factors is
To find concavity we need to find the second derivative.
Use quotient rule to find f'(x)=4/(x+3)^2
Then use chain rule to find f''(x)=-8/(x+3)^3
To find potential inflection points, we need to find all x values where the second derivative is equal to 0 or is undefined.
Set the numerator and denominator equal to 0 and solve.
(x+3)^3=0
x+3=0
x= -3
Now plug a value less than -3 and greater than -3 into the second derivative to find where the concavity is upward (positive number).
Since f''(-4) is positive, that means that f(x) is concave up on the interval (-infinity, -3).
