The graph of y = | f(x) | can be obtained as follows:

(a) Draw the graph of f(x)

(b) Reflect the part of the y = f(x) graph _________________

• about the line y = x

• below the x-axis, in the x-axis

• above the x-axis, in the x-axis

• about the x-axis

If | x +2 | = 3

• x + 2 = 3

• x + 2 = 3

  AND

  x + 2 = -3

• x + 2 = 3

  OR

  x + 2 = -3

• No answer
