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.

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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