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)

whatare you sayig

step-by-step explanation:

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
