The starter is revision of completing the square. If f'(x) = 0 and f”(x) < 0, then there is a maximum turning point If f'(x) = 0 and f”(x) = 0, then there is a horizontal point of inflection provided there is a change in concavity Here are a few examples to find the types and nature of the stationary points. Local maximum point. The turning point of a graph is where the curve in the graph turns. I have the question "Find the coordinates of the turning points of the following curve and sketch the curve Y = X^2(-2X - 4)" Here is my attempt is this correct ? If A = 2x + 3)' + xy, write A as a quadratic in x. The value f '(x) is the gradient at any point but often we want to find the Turning or Stationary Point (Maximum and Minimum points) or Point of Inflection These happen where the gradient is zero, f '(x) = 0. First, change the equation to this form, y=2x^2-4x+1 a=2,b=-4,c=1 the x-coordinate is equal to -b/2a = -(-4)/2*2=1 Let x + y = 13, where x, y > 0. ... test that this turning point represents a minimum. Increasing point of inflection. A turning point is a point of the graph where the graph changes from increasing to decreasing (rising to falling) or decreasing to increasing (falling to rising). 0. pos. line segment ab is the diameter of circle O whose center has coordinates (6,8) . dy/dx = 2x+3 and we set this equal to zero.
