Provide an appropriate response.Without graphing, explain the differences between the graphs of
y = (x - 5)2, and y = (x + 5)2.
What will be an ideal response?
All graphs are the same shape. The graph of y = x2 - 5 is shifted 5 units down, the graph of y = x2 + 5 is shifted 5 units up, the graph of y = (x - 5)2 is shifted 5 units to the right, and the graph of y = (x + 5)2 is shifted 5 units to the left.
