Approximating Point of Intersection

Section 3.3
Question 17



1. How do I approximate a point of intersection by looking at this graph?

2. To equate f(x) = g(x) means to do this:

2^x = 8

Yes?

 

yes

 

How do I approximate a point of intersection by looking at this graph, any graph?

 

you look first how long is each unit
in your example you can see that units on x and y axis go -4,-2,0,2,4 and approximate a point of intersection is at (2,2)

 

I will try this later on my meal break.
