How can you sketch the graph y = |x| - 2 ?
A)Translate the graph of y = |x| two units left
B)Translate the graph of y = |x| two units right.
C)Translate the graph of y = |x| two units down.
D)Translate the graph of y = |x| two units up.
The correct answer is "C"
To see why......note that if we put 0 into the parent function, y = l x l, then y = 0.
And if we put 0 into l x l - 2, we get y = -2. Thus, the original function is shifted down 2 units.
