Question

Given the parent function

Answer 1

Translated up 3 units because k determines if the function will move up or down. If it’s positive it will go up, and if it’s negative it will go down.

Answer 2

A

Explanation:

Function transformations are easy to do when you remember four rules:

• adding or subtracting in the function moves it left and right
• adding or subtracting outside the function moves it up or down
• multiplying and dividing to the function stretches or compresses it

Here the 3 is being added to the function outside the function. This shifts the function up 3 units.
