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:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.
Answer: 65%, 195 children
Step-by-step explanation: To get this, we just do 100-35 to get 65 percent. We can calculate this further, and do 300*0.65, and we get 195. Thus, there were 195 children.
