answer the following

Q 1. When completing the square you should factor out "a" from all terms. O False O True W Q 2. Complete the square and list the key features. Be sure to show and explain all work. -direction of opening -vertex -y-intercept -Max or Min vertex? Ax) = 2x' +4x+1W Q 3. Without graphing, Find the vertex and y-intercept of the quadratic function: Ax) = 4x' - 8x +2 O vertex (1, -2) and y-intercept (0, 2) O vertex (-1, 2) and y-intercept (0, 2) O vertex (1, 2) and y-intercept (0, 2) O vertex (-1, 2) and y-intercept (2,0) W Q 4. Given the equation f(x) = 3x - 6x + 2, the vertex is a maximum located at (-1, 1) O True O False
