Question

Describe the intervals on which the function f is positive, negative, increasing and decreasing. Them describe the intervals on which the function A is positive , negative, increasing and decreasing

Short answer

The function f is positive on the interval$(0,\infty )$

The function f is is decreasing on the interval$(0,1)$

The function f is increasing on the interval$(1,\infty )$

And

The function f is positive on the interval$(0,\infty )$

The function f is is decreasing on the interval$(0,1)$

The function f is increasing on the interval$(1,\infty )$

Step-by-step solution

Given information

We are given a function f and a function A

Explanation

The function f is positive on the interval $(0,\infty )$

The function f is is decreasing on the interval $(0,1)$

The function f is increasing on the interval $(1,\infty )$

Similarly

The function f is positive on the interval$(0,\infty )$

The function f is is decreasing on the interval$(0,1)$

The function f is increasing on the interval$(1,\infty )$
