(a) The standard form for a quadratic expression is x2 - 12x + 32. Which of the following are equivalent to the given expression? O Factored form: (x - 4) (x - 8) O Factored form: (x - 4) (x + 8) O Vertex form: (x - 6) + 4 O Vertex form: (x - 6)- - 4 O Vertex form: (x + 6)2 - 4Find the number of x-intercepts of y = 1.5(x - 25)2 without changing the form of the right-hand side. There is/are x-intercept(s).Put the function y = (3x - 9)2 + 3 in vertex form f (x) = a(x - h)2 + k and state the values of a, h, k. y = 3(x - 3)2 + 3 y = 9(x - 3)2+3 y= 9(x - 9)2+3 Form 1 Form 2 Form 3 Choose the correct formula number from the table above: a = 2 3 h = i k = iWrite the expression (x - 7) - 1 in factored form and identify a, r and s. Factored Form a = r= S
