Recall the general form of an absolute value function and the roles of each constant in it.
G
| Constant | Value of the Constant | Transformation |
|---|---|---|
| a | a<-1 | stretch + reflection |
| -1 | compression + reflection | |
| 0 | compression | |
| 1 | stretch | |
| h | h<0 | translation to the left |
| h>0 | translation to the right | |
| k | k<0 | translation down |
| k>0 | translation up |
With this in mind, we can see that k and h from the general form are the values that are of interest to us. The vertical translation 4 units up will go where k goes. y=|x-1|+ 4 Now, let's consider the horizontal translation. We want to translate the graph 3 units right, so h is equal to 3. y=|x-1- 3|+4 Note that, in our case, the parent function already had a subtraction inside the absolute value. Therefore, to translate this function 3 units to the right, we need to subtract 3 from the whole expression in the absolute value symbols. Finally, let's simplify the obtained equation. y=|x-1-3|+4 ⇕ y=|x-4|+4 This corresponds to option G.
