Q. 2 - Calculus

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

Step-by-Step Solution

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 1: Given information

We are given a function f and a function A

Step 2: 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 $(1,\infty )$
