The graph shows the functions f(x), p(x), and g(x):
1 answer:
Part A:
The solution of p(x) and g(x) is the point of intersection of the two lines. Reading this off the diagram we can see that the point of intersection is (4, -3)
-----------------------------------------------------------------------------------------------------------------
Part B:
A solution for g(x) is any pair of coordinates that lie on the line g(x). We can choose any two coordinates; (5, -5) and (-6, 17)
--------------------------------------------------------------------------------------------------------------
Part C:
The solution to g(x) = f(x) is the point of intersection. From the graph, the point of intersection is (0, 5)

Step-by-step explanation:
I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as
which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:
which gives us, in the end,
y = 9460
