The function is defined only if
. So, the leftmost point is
, and we have

So, the first point is 
The three additional points seem arbitrary, so let's choose
. We have:

So, the second point is 

So, the third point is 

So, the fourth point is 
Scalene,Acute i think it is haha
32 ft
this is meters per second >>> 9.7536
Answer:


And we can find the limits in order to consider values as significantly low and high like this:


Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
For this case we can consider a value to be significantly low if we have that the z score is lower or equal to - 2 and we can consider a value to be significantly high if its z score is higher tor equal to 2.
For this case we have the mean and the deviation given:


And we can find the limits in order to consider values as significantly low and high like this:


What kind of operation is this ? it just says x and a nine.
