I don't know what you mean by "critical points". However, I'm going to list all the important points in this equation-
x intercepts: (-1 ,0) and (5,0)
vertex: (2,-9)
y intercept: (0,-5)
Hope this helps!
Answer:
V220 should be the answer
This is simple division:

So, plug it into your calculator and you get:

Your answer's that
it takes 4.5 hrs for the surveillance run.
Step-by-step explanation:
Given inequality is
.
To graph that inequality, first we need to graph the line
. Then shade it for the inequality symbol <.
Graphing line can be done using two points.
plug x=0 into
, we get:

Hence first point is (0,2)
Similarly plug any random number for x say x=4, we get:

Hence first point is (4,5).
Now we just need to graph both points and join them by a dotted line. because we have < not <=.
Next part is to test for shading.
Which can be done using any test point which is not on the given line. Say (0,0)
plug x=0,y=0 into
.


0<2
which is true, hence shading will be in direction of test point (0,0).
Hence final answer will be the choice which looks like the graph attached below;
