4. the graph of the quadratic function is defined by the equation. y = a(x – h)^2 + k When a is not equal to 0, the h is not equal to 0, and k is not equal to 0, it will be a parabola with the highest point or return the minimum point is at (h, k) and with axes symmetry is the straight line x = h. Summary of the characteristics of a given graph with equation y = a (x-h) ^ 2 + k. When a > 0! "parabola face The lowest point is at (h, k) = k minimum. When a < 0, upside down parabola. The highest point is at (h, k) = k. If k > 0 return above the X axis points. If k < 0, return the X axis points. Axial symmetry is a straight line, x! = x = axial symmetric equation is h h. If h > 0 is on the left hand side of a symmetry axis, the Y axis. If the < 0 h on the right of the symmetry axis, the Y axis. If a k have the same sign and graph the X axis is not cut. If a & k has a different mark X axis graph.5. the graph equation y = ax by ^ 2 + bx + c when a is not equal to 0. Graph, equation should be written as y = a (x-h) ^ 2 + k will make the write graph. From the equation y = ax ^ 2 + bx + c could change as y = a (x-h) ^ 2 + k by completing knowledge.
