WebSOLUTIONS TO GRAPHINGOF FUNCTIONS USING THE FIRST AND SECOND DERIVATIVES SOLUTION 1 :The domain of fis all x-values. f'(x) = 3x2- 6x = 3x(x- 2) = 0 for x=0 and x=2 . See the adjoining sign chart … WebQuadratic equations are written in vertex form as: y=a (x-h)^2+k. where (h,k) represent the vertex of the parabola, and the sign of a represents if the graph of parabola is open upwards or downwards. In your equation y = - (x-2)^2+3, Vertex (h,k)= (2,-3) Since a=-1, this tells us that the graph will be open downwards.

WebExample 1: Sketch the graph of the quadratic function Solution: In this case we have and STEP 1: Find the vertex. To find x - coordinate of the vertex we use formula: So, we substitute in for and in for to get To find y - coordinate plug in into the original equation: So, the vertex of the parabola is STEP 2: Find the y-intercept. WebOn the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 …
