The graph below shows a company's profit f(x), in dollars, depending on the price of erasers x, in dollars, being sold by the company:
300 + f(x)
270
240
210
180
150
120
90
60 +
30
Part A: What do the x-intercepts and maximum value of the graph represent?
What are the intervals where the function is increasing and decreasing, and
what do they represent about the sale and profit? (6 points)
Part B: What is an approximate average rate of change of the graph from x = 1
to x = 4, and what does this rate represent? (4 points)
(10 points)

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
