Question

The graph of f(x) = |x – h| + k contains the points (–6, –2) and (0, –2). The graph has a vertex at (h, –5). Describe how to find the value of h. Then, explain how this value translates the graph of the parent function.

Answer 1

 The absolute value function is symmetric. Since the points (–6, –2) and (0, –2) have the same output, the points are the same distance from the line of symmetry. Between –6 and 0 is the value of –3. So, the vertex must have an x-coordinate of –3, which is the value of h. This would translate the graph of the parent function 3 units to the left.

Answer 2

Answer:SAMPLE QUESTION The absolute value function is symmetric with its vertex on the line of symmetry. Because the points (–6, –2) and  (0, –2) have the same output, the points are the same distance from the line of symmetry. Midway between –6 and 0 is the value of –3. Therefore, the vertex must have an x-coordinate of –3, which is the value of h. This would translate the graph of the parent function 3 units to the left.
