BEST ANSWERS= BRAINLIEST 3. Blackberry is also in the business of selling phones. The data for the profit that Blackberry makes on selling tablets is represented by the following equation with profit being P(b) and b being number of blackberry phones sold (both variables in millions):

P(b) = -x2 + 8x – 8

a. Use the quadratic formula to solve the equation. What do these points tell us about the graph?

b. Complete the following table. Based on the table, estimate the vertex for the function. Is the vertex a max. or a min. point?

Blackberry: Profit from Smart Phones Sold

Smart Phones sold (in millions) b Profit (in millions of dollars) P(b)
-1 ?
0 ?
2 4
3 ?
4 ?
5 7
6 ?

c. Sketch a graph for Blackberry. Label the x and y axis (for b and P(b))

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
