Graphing Reciprocal Functions

Graphing Reciprocal Functions Consider the function Without graphing, can you find any limitations for x? The denominator of a fraction can never equal 0, so How about limitations for y? Since ,

The graph and its parts End Behavior: Branches Increasing/Decreasing: Domain and Range: Asymptotes x=0, y=0

Transformation of inverse variations Given the parent function What do you think the following transformations will do to the function? 1. 2. 3. Check your answer in your calculator. (Were you right?) What do you notice about the asymptotes for the transformed functions?

Describe the transformations, name the asymptotes, domain and range Try some on your own:

Examples 1. Write the equation if the parent function has asymptotes at x = -2 and y = 3. 2. For the same parent function, write the equation for the translation of that is 4 units left and 5 units up

Examples 3. Write the equation if the parent function has asymptotes at x = -1 and y = 5. 2. For the same parent function, write the equation for the translation of that is 7 units right and 2 units down.

Examples 1. Write the equation if the parent function has asymptotes at x = 8 and y = -4. 2. For the same parent function, write the equation for the translation of that is 7 units up and 2 units left.
