Question

a) Determine increasing interval(s) of the function if it exists.

b) Determine decreasing interval(s) of the function if it exists

c) How is the graph of the entire function different from the graph for the real-life situation

Given that, the function is C (n)
600+115n
n
600+115n
Sketch the graph of the function C (n)
as shown below,
n
C(n)
400
C(n) = 600 + 115m
200
y= 115
-150
-100
-50
50
100
150
(-5.217, 0)
x= 0
-200-
-400
From the above
figure it is clearly observed that, the x-intercept is -5. 217, the vertical asymptote is x=0 and
the horizontal asymptote is y=115.
