1.

Use the graph that shows the solution to f(x)=g(x) .

f(x)=1/x   (on side)−2

g(x)=x−2

What is the solution to f(x)=g(x) ?

−1

1

2

3 2. Use the graph that shows the solution to f(x)=g(x) .

What is the solution to f(x)=g(x) ?

x=−1

x = 0

x = 2

x = 3 3.

Use the graph that shows the solution to f(x)=g(x) . What is the solution to f(x)=g(x) ?

x = 0

x = 1

x = 2

x = 4 Thank you very much!!! Need help on these practice concepts because I am confused lol

First one

g(x)  is the same on both graphs

f(x) = 1/x - 2      is shown on the top graph

So....the top graph is correct

The intersection points are  - 1  and 1

P.S. - If you allowed to......Desmos is a pretty good graphing utility that might help you

Thank you much! I will check out the desmos graphing system as well. It could come in handy for understanding problems like these!!

Second one

If we put   0 into f(x), we get 2

Thus the point (0, 2)  is on the graph of f(x)

So....the first graph must be correct

The intersection point  is just  at   0   Feb 27, 2019

Last one

f(x) is the same  on both graphs

If we put 0 into 2^x  we get 2^(0)  = 1

So...the point (0, 1) is on the graph of  g(x)

So...again....the top graph is correct.....and the intersection points are at 0 and 2   Feb 27, 2019
