Question

Which of the following equations is the translation 2 units down of the graph of y = |x|?

y = |x - 2|
y = |x + 2|
y = |x| - 2
y = |x| + 2

Answer 1

Please help!

Answer 2

C

Answer 3

Let y = f(x).
f(x + a) means shifted by a units in the direction of x-axis
f(x) + a means shifted by a units in the direction of y-axis
In this question,
y = |x|
f(x) = |x|
The question wants you to shift the graph down, which is in the direction of the y-axis, so
f(x) - 2 = |x| - 2
