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). (Increasing because the quadratic coefficient is negative, so the turning point is a maximum and the function is increasing to the left of that.) The calculator will generate a detailed explanation for each of these computations. Sketch the graph of the quadratic function, In this case we have $a=1, b=2$ and $c=-3$. Transformations of the graph of the quadratic can be explored by changing values of a , h and k . \text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } A maximum turning point is a turning point where the curve is concave up (from increasing to decreasing ) and $f^{\prime}(x)=0$ at the point.
