Transformations of Rational Functions

Recall the two parent functions from our last class (page 11 and page 14) and your NearPod assignment.

​Now recall the transformation rules you learned during first semester.

TRANSFORMATION RULES

​Now lets put those two concepts togethers

Multiple Choice

Which equation would shift the quadratic function

$$f\left(x\right)=x^2$$  up 3 units and to the right 4 units.

• $$f\left(x\right)=\left(x+3\right)^2+4$$  

• $$f\left(x\right)=3\left(x-4\right)^2$$  

• $$f\left(x\right)=\left(x-4\right)^2+3$$  

• $$f\left(x\right)=\left(x+4\right)^2+3$$  

Multiple Choice

Describe the transformation:

$$f\left(x\right)=\left(x+3\right)^2-2$$  

• right 3, down 2

• up 3, left 2

• left 3, up 2

• left 3, down 2
