The function that correctly returns grades from 60 percent to a 100 percent is f(x) = [[(x - 50)/10]]
<h3>How to determine this function</h3>
The question tells us that the students do not fail and they do not get a 100 percent score either.
Hence there is no need for worry if the grade is at 5.0 or less than 1.
For example we have
x = 82.976
f(82.976) =[[(82.976-50)/10]
This would then be 3.29
This is then = 3.0
This function is not an odd function and it is not an even function. This is because the domain does not have negative values.

It’s going to be 400 dollars, 20percent is 100 dollars
The answer is x=9 because if you do 3x+-2 that gives you 1 and 1 divided by 9 is 9 and you get that by getting rid of your 6 first and adding it to the 3 from 3(x+1)
