Find the coordinates of the stationary points on the graph y = x 2. solve dy/dx = 0 This will find the x-coordinate of the turning point; STEP 2 To find the y-coordinate substitute the x-coordinate into the equation of the graph ie. So if we differentiate y=x 3-6x 2 +16 we will obtain the gradient function of this curve. Finding coordinates of the turning point in a parabola is the same as finding the coordinates of the vertex. Then, to find the coordinates of the turning point, we need the halfway point between the roots, which is \dfrac{-2+(-3)}{2}=-2.5 . Find the coordinates of the turning point and determine wether it is minimum or maximum. The turning point on the curve y =x^2 - 4x is at? y=xlnx-2x The answer in the book says the co-ordinates are (e,-e), the closest I have come is (1/lnx,-1/lnx) which works if 1/lnx=e, but I don't think that it does. Use the first derivative test: First find the first derivative #f'(x)# Set the #f'(x) = 0# to find the critical values. This is because the function changes direction here.
