0 and 1 are in the range. So is any real r less than 1
thanks but i have to find a number that is not in the range.
I did not know what your "nto" meant. Any number greater than 1 is NOT in the range
i was thinking that it would be any number less than O. why is that not correct?
Numbers less than zero ARE in the range of possible f(x) values. For example, if x = 2, f(x) = -3
