Supposefis a one-to-one function whose domain is given by the inequality -4 ≤x ≤5.

The range offis given by the inequality 0 ≤f(x) ≤9.

What is the domain off-1?

Would the answer be -9 ≤f-1(x) ≤0 or -4 ≤f-1(x) ≤5 (Headbang)

Suppose

*f*is a one-to-one function whose domain is given by the inequality -4 ≤*x ≤*5.

The range of*f*is given by the inequality 0 ≤*f(x) ≤*9.

What is the domain of*f*-1?

Would the answer be -9 ≤*f*-1(*x) ≤*0 or -4 ≤*f*-1(*x) ≤*5 (Headbang)

so, does that mean the answer is -4 ≤

*x ≤*5???? - Nov 15th 2009, 02:59 PMe^(i*pi)

I think its your first answer,

0 ≤

*x ≤*9 maybe its this? haha this is like the hardest math problem on this forum >< - Nov 15th 2009, 05:19 PMskeeter
