Plz help me!! Part A: What do the x-intercepts and maximum value of the graph represent?
Part B: What are the intervals where the function is increasing and
decreasing, and what do they represent about the sale and profit?
Part C: What is an approximate average rate of change of the graph from x= 1
to x = 3, and what does this rate represent?

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day

just took the test and my answers down below!

step-by-step explanation:
