can someone PLEASE help me out writing this equation in vertex form?

4 Answers

• y = a(x – 4)² – 6

  => -4 = a(5 – 4)² – 6

  => -4 = a – 6

  i.e. a = 2

  so, y = 2(x – 4)² – 6

• You are not dumb. Dumb means you cannot talk.

  You are bright enough to ask for help. I call that SMART.

  Y = A(X – H)² + K

  Vertex = (H , K) = (4 , -6)…………H = 4 and K = – 6

  Point is (X , Y) = (5 , -4)…………X = 5 and Y = – 4

  Now solve for A by substituting in the values of H , K , X , Y

  – 4 = A(5 – 4)² – 6

  +6……………….+6

  2 = A(1)²

  A = 2

  For the final answer replace A , H , K into the original equation

  Y = 2(X – 4)² – 6………………ANSWER

  Let me know if you have questions on this problem or any other math problems.

  I am an excellent math teacher/tutor specializing in making students

  faster…..smarter……and better looking like myself. Okay, just faster and smarter
