The graph below shows a company's profit f(x), in dollars, depending on the price of goods x, in dollars, being sold by the
company:

Part A: What do the x-intercepts and maximum value of the graph represent?
prefent? ?
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?

Answers

Maximum value is maximum profit
The x intercepts are the prices that profit equals zero

B
Increasing from - infinity to 3 and decreasing from 3 to infinity. When price is less than 3 every increase in price results in an increase in profit. When price is greater than 3, every increase in price results in a decrease in profit. So what this is saying about sales is that when you set the price beyond 3 bucks, the amount of people willing the buy at that price drops such that you start making LESS profit because less people are willing to buy, and the lack of buyers offsets the additional price that the others are paying.

C
The average rate of change is 60 and this represents the increase in profit per increase in price

D. There are points on the graph with the same [tex]x[/tex]-coordinate but different [tex]y[/tex]-coordinate.

Step-by-step explanation:

A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.

Hence, correct answer is D.

Jordan and Roman travel the same route to work. Jordan leaves for work one morning and drives at a rate, r, of 56 mph. Roman leaves the house soon after, when Jordan has already traveled 2 mi. Roman drives at a rate of 60 mph. How long after Jordan leaves home will Roman catch up to her? How many miles into their commute will this occur?

Which system of equations models this problem?

d = 56t
d = 58t

d = 56t
d = 62t

d = 56t
d = 60t – 2

d = 56t
d = 60t + 2

Answers

Step-by-step explanation:

D= 56t

D= 60t -2

D= Distance T=time d = 56t (Jordan) d = 60t - 2 (Roman)

d = 56t d = 60t - 2

56t = 60t - 2 d = 56(1/2) d = 60(1/2) - 2

-60t -60t d = 28 d = 30 - 2 = 28

-4t = -2

t = 1 / 2

Which equation represents the line that passes through the point (-3, 2) and has a slope of 2


Why is it the right answer?

Answers

Step-by-step explanation:

y = mx+b

y - 2 = 2(x - -3)

y-2 = 2x +6

y = 2x +8

Answer:

y=2x+4

Step-by-step explanation:

okay so basically we have a slope value (m=2) and a point (-3,2). we can put these into the point slope formula, which is

(y-y1)=m(x-x1)

(we need to leave a y and an x in order have the actual equation)

so we just plug in the values (y1=2 ; x1=-3 ; m=2)

(y-2)=2[x-(-3)]

y-2=2(x+3)

y=2x+6-2

y=2x+4

Here ,

[tex] {y}^{6} \div {y}^{2} [/tex]
