PLEASE HELP THIS IS A FINAL ALGEBRA!! :( You will compare profit functions for different companies from selling smart phones.
X-axis = Number of Smart Phones sold (in millions) = g (for galaxy phone)
y-axis = Profit (in millions of dollars) = P(g)

1a. Label the line as “Samsung”, the x-axis and the y-axis.

b. Describe the key features of the graph. Key features include concavity, x and y-intercepts and the vertex.

c. Is the vertex a max. or min. point? Describe what the vertex means in terms of this problem.

d. Create an equation in completed the square form. Then translate this to standard form.

Standard form  f(x) =

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

the answer is b
