Questions and Answers
- 1.
Can you identify the equations of all of the different colored functions in the graph below? All are related with only minor adjustments to the "parent function". If you need some help to get started, the "parent function" is one of the equations from a previous question. Your tasks: #1) Enter the equation for each of the 5 different functions on the coordinate plane below. #2) Identify which function (by equation and by color), I used as the "parent function." - 2.
