In the function: f(z) = ax + br + c .. to change from standard form to vertex form you must complete the square. Isolate the a and b term with parentheses: f(x) = (ax2 + bx) + c When a = 1, divide b by 2 and then square the quotient: Select options below 1. Select Option . this value to the expression in the parentheses and Select Option . it from the constant coutside the parentheses. 2. You are basically adding Select Option . to the function.After completing the square for the function: f(x) = 12 - 12x - 9 ..what are the values of h and k for the function's vertex form? y = a(x - h) +k 1. Give the value of k in the function's vertex form. Do not include spaces in your response. Type answer here. Be careful with spelling. 2. Give the value of h in the function's vertex form Type answer here. Be careful with spelling
