<u>Approximate Roots of Functions:</u>
We are required to find the root of
Let's construct a function
Reducing:
The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)
We'll move up on x=1.52
We are closer to the solution, let's try some more up
This value x=1.54 is close enough to the solution of the original equation
From the options given, is the closest to our solution
