Which of the following is the equation of the axis of symmetry of the quadratic equation y = 2x^2 + 24x + 62?
An axis of symmetry is the line a parabola forms from the highest or lowest point. First, take -b/2a in this case, -24/4. That is your axis of symmetry. (X=23 is an example of this)

Which of the following is the vertex of the quadratic equation y = 6x^2 – 24x 32?
Weegy: y = 6x^2 -24x + 32 y = 6(x^2 - 4x + 4) + 8 Notice 2 things: 6 is factored out, [ leaving the x^2. The constant 32 is split up into 6*4 + 8. The trick is to make the part in parentheses the square of a binomial: y = 6(x-2)^2 + 8 Now you already know that y=x^2 has a vertex at (0,0) So the (x-2) means it is shifted 2 units to the right, and the +8 means it is shifted 8 units up. From there you should know where the vertex is. You also know what the line of symmetry is if you know where the vertex is. ] (More)
