Also, the vertex is at the axis of symmetry of the parabola (ie it divides it in two). The parabola is f(x) = y = - 2x 2 - 4x + 3. Change the equation to produce a graph concave down that shares the same vertex.
I know how to get the vertex but I always mess up when it comes to graphing the exact point or points. Hence its origin is (0, 0) Since the coefficient of x^2 is negative, the parabola opens down. Graph a parabola by finding the vertex and using the line of symmetry and the y-intercept.
Maximum or minimum point of a parabola Since a>0, the vertex is the minimum point and the parabola opens upward. You can put this solution on YOUR website!. This problem has been solved!.
