Answer to Problem 35AYU
Solution:
a.
b.
Explanation of Solution
Given:
The given figure is
Formula Used:
The points in a graph are written in the form .
The equilibrium point of 2 functions is the point at which the functions are equal and therefore, the 2 functions meet at the equilibrium point.
Calculation:
a. We have to solve the equation .
From the graph, we can see that is the equilibrium point.
Therefore, at , we have .
Thus, on solving the given equation, we get the solution as .
b. We have to solve the equation .
On splitting the above inequalities, we get and .
We know that when we have .
Therefore, when , we get .
This can also be written as ----- (1)
The equilibrium point for and is .
Therefore, when we get .
Thus, when , we have ----- (2)
Now, on combining equations (1) and (2), we get the solution for as .
