Question

Suppose f(x)=-x^2+1, and the domain of the funtion is the real numbers.  Give an example fo a number that is nto in the range of f.

drwls · Answer

0 and 1 are in the range. So is any real r less than 1

Renee · Answer

thanks but i have to find a number that is not in the range.

drwls · Answer

I did not know what your "nto" meant. Any number greater than 1 is NOT in the range

Renee · Answer

i was thinking that it would be any number less than O. why is that not correct?

drwls · Answer

Numbers less than zero ARE in the range of possible f(x) values. For example, if x = 2, f(x) = -3
