4-140.
  1. Sketch the graph of y = 2(x − 1)2 + 4. Homework Help ✎

    1. Now rewrite the equation y = 2(x − 1)2 + 4 without parentheses. Remember the order of operations!

    2. What would the difference be between the graphs of the two equations above? This is sort of a trick question, but explain your reasoning.

    3. What is the parent of y = 2(x − 1)2 + 4?

    4. What is the parent of y = 2x2 − 4x + 6?

y = 2x2 − 4x + 6

Where is the vertex of y = 2(x − 1)2 + 4? Or y = 2x2 − 4x + ?
What are their stretch factors?
