The parent function is translated units up and units right. Write the equation of the translated function.
Start from the parent function. The graph of is a V with vertex at the origin and arms of slope . Every absolute-value graph in this family is this same V placed somewhere else.
Shift 2 units right. Replace the input with :
The minus sign produces a shift to the right. A quick way to see why: the corner occurs when the inside is zero, and happens at , two units right of the original corner.
Shift 4 units up. Add to the whole expression:
Read off the general pattern. The result fits the standard vertex form
so lives inside with a minus and lives outside with a plus — the single rule behind every problem of this type.
Verify with points. The parent point should land at : the new formula gives . The parent point should land at : the formula gives . Both arms keep slopes , confirming that a translation changes position but never shape.
