3.4 Transformation of Cubic and Quartic Functions

Question 1

how to find the k value

Answer 1

the k value is flipped when writing the transformations

Question 2

how to find the x-intercepts of a function

Answer 2

set y equal to zero and isolate for x
exact value has a square root
decimal approximating is the answer in decimal form

Question 3

how to describe transformation when a and k arent given

Answer 3

1. write the transformation equation
2. state parent points of the parent function
3. If we assume only a and no k k=1
4. plug numbers into the transformation equation
5. Sub in a point in the equation to solve for a
6. If we assume k and a=_ original a
7. Plug in a point a solve for k

if there’s a square root, it becomes plus and minus
