Seraph in is comparing the graphs of the parent function y = x^2 and the function y = 6(x − 3)^2 − 8. He makes the following statements about the new function.
• Stretch vertically by a factor of 6.
• Translate 3 units right.
• Translate 8 units up.
Are Seraphin's statements correct? Explain why or why not.
A. No; Seraphin's first statement is not correct. Because the a-value is positive, the graph should be stretched horizontally by a factor of 6.
B. No; Seraphin's third statement is not correct. Because the c-value is positive, the graph should be translated 3 units to the left.
C. No; Seraphin's third statement is not correct. Because the d-value is negative, the graph should be translated 8 units down.
D. Yes; the statements are all correct.
