The "int()" operator in your calculator is the "greatest integer function." It returns the greatest integer less than or equal to the operand and is written using square brackets: [x] or [[x]]. For example, it would give back 82 for [[82.976]]. In Smalltown, AZ the students receive grade points as follows: 4.0 for any grade 90% or higher. [90,100) 3.0 for any grade 80% or higher. [80,90) 2.0 for any grade 70% or higher. [70,80) 1.0 for any grade 60% or higher. [60,70) (Notice: students NEVER fail! And students never get 100%!)

The function that correctly returns grades from 60 percent to a 100 percent is f(x) = [[(x - 50)/10]]

How to determine this function

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.
