ANSWER
To graph the function

follow the steps below.
1. Find y- intercept by plugging in

.

is on the interval,

, so we substitute in to



Hence the y-intercept is

2. Find x-intercept by setting

This implies that

on

or

on

We now solve for

on each interval,

on

or

on

But observe that

does not belong to

This means it can never be an intercept for this piece-wise function.
Hence our x-intercept is

3. Plotting the boundaries of the interval.
For

on



.
This point

coincides with the x-intercept.


So we have the point

. But note that

does not belong to this interval so we plot this point as a hole.
For

on



So we plot



So we plot

also as a hole.
Plotting all these points we can now graph the function,

See attachment for graph.
Answer:
I think 60 - 1200 but i am not conform
11.6, if you need a decimal. it's in between 11 and 12
Answer:
B and D
Step-by-step explanation:
A is false as it would be 3.08 when rounded.
C is false as it is rounded to the tenth not hundredth.
Im not sure what the question is asking but my guess would be c)18.
