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)
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) =

y-axis = Profit (in millions of dollars) = P(g)

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

-81 -56 -27 0 81
