1. Min as you put larger values of x the function goes on decreasing thus for very large value of X f goes on decreasing
Thus min is - inf
Max when x is min which is just lesser than 2 as x greater 0
Thus range is open - inf to open 2

Domain is the real values which are allowed to compose the given function
F = - mod (x) allows all real values of X as domain but in the range all the negative values. 0 to - inf as mod x gives positive values - of mod x gives all negative
2. For t to be real 9- squ (x) must be greater 0
9 - squ (x) greater 0
Squ ( x) less than 9
Factorize x- 3 × x+ 3 less 0 x between -3 to 3 . Range is from min to max
Min is 0 when x=3 Max is 3 when x= 0
Thus from 0 to 3 both including.

When 1 value of y gets mapped from 2 values of X makes f a non function
Let easy be the way when a+ b = 0 , a = -b
ab = - a×a which is multiple
E.g. - 4 = -2× 2 -2 + 2 = 0
-9 = -3×3 -3 + 3 = 0
Hence this is many to one which is not a function
