Which of the following equations is of the parabola whose vertex is at (2, 3), axis of symmetry parallel to the y-axis and p = 4? a.)y-3 = 1/16 (x-2)^2 b.)y+3 = -1/16 (x+2)^2 c.)x-2 = 1/16 (y-3)^2

What is the difference between the predicted value and the actual value

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?
