Discussion Instructor: Jodin Morey moreyjc@umn. sometimes it will just be a curve you know, like y = sin(x) or y = x2, but they have stretched it and moved it a bit, or combined it with another function you also know. If we have a graph of f , we will see what we can conclude about the we can see by switching to the representation x = y3). 1) without recourse to computational aids, by combining various techniques we have been dis-cussing. If f is 4. An asymptote is a line which is tangent to a curve at infinity. Concavity and Curve Sketching nctio Note. Recall: oints: oints c of f ( x where f0( c es existr f0( c 0. from Example 1.

The computer can do this much better simply by plotting many points so why bother with our piddly sketches? One reason is Curve Sketching The first derivative of a function tells us over which intervals the function is increasing and decreas-ing, and allows us find the extrema of a function, which gives us some idea of how a Asymptotes Asymptotes provide information about the behavior of curves in the large. Curve Sketching with y0 and y00: Putting it all together We now have enough techniques in hand to sketch the graph of a function using the rst and second derivative.

(a) Find the horizontal asymptotes, if any} by checking lim f (x) and 11m f (x). Compute some points on the curve, especially any that are easy to calculate. The document outlines the process of curve sketching, including finding intercepts, asymptotes, relative maxima and minima, and points of inflection. Find the domain and range of f. Understanding the Fundamentals of Curve Sketching in Calculus I Curve sketching in Calculus I is the process of using information derived from a function's properties to accurately represent its graph. It outlines the procedure for sketching curves, Unit 2 Outline Unit Goal: Make connections, graphically and algebraically, between the key features of a function and its first and second derivatives, and use the connections in curve sketching. We then have y00 = 2 9x 5=3 which is positive when x < 0 and positive when x > 0, so the function chan es convacity at x 0 and th 2. Curve sketching We are already familiar with using a number of algebraic techniques to sketch the graph of a function. 5 Curve Sketching Guidelines for sketching a curve w/o a calculator Determine the Domain Identify intercepts (y intercept f(0) where x=0, x intercept is where y=0) Symmetry (odd,even, periodic) First Derivative Test Finding local extrema can be useful for sketching curves. We will use what we have learned about Marius Ionescu 4. We want the graph to be qualitatively correct, but not necessarily to scale. In particular, it can be applied to functions which involve the exponential function xi—*-ex in some way. Intercepts: The y -intercept is f (0 ) and this tells us where the Techniques for carefully sketching functions When sketching a graph of a function f x , you want to clearly indicate all the important features of the function, including its domain, the x- and y-intercepts Gostaríamos de exibir a descriçãoaqui, mas o site que você está não nos permite. MATH 122: Calculus I Curve Sketching Ralph A. (b) Find the vertical asymptotes, if any. This topic has been discussed under ‘Quadratics’, but examination questions might also ask for sketches of other types of functions, such as cubics or reciprocals. When the graph of g is a straight line, we call this a slant asymptote of f. pdf), Text File (. When graphing a function f you want to make clear all of the following, if they make sense for the function. This document provides an overview of techniques for sketching curves based on their algebraic equations. We can also notice that because all the powers of x are odd, the function f is odd; f( x) = 3( x) ( x)3 = 3x + x3 = f(x). 1 Significance of The First Derivative to Curve Sketching You will now consider the application of differentiation to curve sketching some curve could easily be sketched with the knowledge of the first Derivatives and Curve Sketching You might want to use Desmos to check your answers for this worksheet.
