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?

 

[MathLover1]

yes

 

[nycmathguy]

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.
