Algebra 2 Unit 7 Lesson 2

5) Choose the best answer. Describe how the graph of f(x)=4/x will differ from the graph of g(x)=1/x

The graph will be "stretched" and enlarged by a factor of four

7) Choose the best answer. Describe how the graph of f(x)=1/x+3 will differ from the graph of g(x)=1/x

The graph will be shifted to the left three units.

6) Choose the best answer. Describe how the graph of f(x)=1/x+5 will differ from the graph of g(x)=1/x

The graph will be shifted up five units.

3) Which is the correct equation for the graph?

f(x)=1/x+3

2) Which is the correct equation for the graph?

f(x)=x'2-5x+6/x-3=(x-3)(x-2)/x-3=x-2
