Curve Sketching 1 Critical Point And Increasing Decreasing Youtube This calculus video tutorial provides a summary of the techniques of curve sketching. it shows you how to graph polynomials, rational functions with horizon. You just take the derivative of that function and plug the x coordinate of the given point into the derivative. so say we have f (x) = x^2 and we want to evaluate the derivative at point (2, 4). we take the derivative of f (x) to obtain f' (x) = 2x. afterwards, we just plug the x coordinate of (2,4) into f' (x). For each interval created, determine whether \(f\) is increasing or decreasing, concave up or down. evaluate \(f\) at each critical point and possible point of inflection. plot these points on a set of axes. connect these points with curves exhibiting the proper concavity. sketch asymptotes and \(x\) and \(y\) intercepts where applicable. We can use the steps we’ve just learned to sketch its curve. begin by finding thse x and y intercepts of the function. x intercepts. y intercepts. 1 1 x 2 = 0 1 = 0 ⇒ no solution. f ( 0) = 1 1 0 2 = 1 y int = ( 0, 1) from this, we can see that f ( x) has no x intercepts and a y intercept at ( 0, 1).
