Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?
-f(x) can be odd or even.
-f(x) can be odd but cannot be even.
-f(x) can be even but cannot be odd.
-f(x) cannot be odd or even.
Solution:
For f(x) is a function
such that if p < q,
f(p) < f(q)
This shows that f is an increasing function
We know that
If f is an increasing function
-f is always a decreasing function
So - f(x) is a decreasing function
For example -
Consider f (x) = x is an increasing function
- f(x) = -x is a decreasing function
It is an odd function and not an even function
Therefore, the statement - f(x) can be odd but cannot be even best described f(x).
Suppose f(x) is a function such that if p < q, f(p) < f(q). Which statement best describes f(x)?
-f(x) can be odd or even.
-f(x) can be odd but cannot be even.
-f(x) can be even but cannot be odd.
-f(x) cannot be odd or even.
Summary:
Suppose f(x) is a function such that if p < q, f(p) < f(q). The statement - f(x) can be odd but cannot be even best described f(x).
