Question
What function g describes the graph of f after the given transformation?
f(x) = IxI; translated 2 units up and 1 unit right
- g(x) = Ix + 1I – 2
- g(x) = IxI + 2
- g(x) = Ix – 2I + 1
- g(x) = Ix – 1I + 2
Hint:
Know what moving up and going right means in terms of function.
The correct answer is: g(x) = Ix – 1I + 2
2 units up means f(x) increases by 2 units.
1 unit right means x decreases by 1 unit.
So, g(x) = Ix – 1I + 2
