DropBoite Posted April 30, 2012 Report Share Posted April 30, 2012 hello! often we're asked to sketch graphs for functions i want to know whether this means draw a proper one on a graph paper or literally sketch one on normal paper? its for four marks so im gyessing the former. thank you!

HiggsHunter Posted April 30, 2012 Report Share Posted April 30, 2012 A graph that is "sketched" should give a general idea of its shape, including relevant features such as intercepts, maxima, minima, points of inflexion and asymptotes.A graph that is "drawn" should have points plotted accurately and joined in a straight line or smooth curve. 1 Reply Link to post Share on other sites More sharing options...

Drake Glau Posted May 1, 2012 Report Share Posted May 1, 2012 Well, you can't "sketch" a graph in math studies because the curriculum does not cover how to find minima, maxima, points of inflexion, and the only asymptotes you know from math studies is just when a denominator is 0 =/If I remember right, they are basic graph shapes shifted a few ways and maybe stretched/squished a little. I remember there being lots of things like "draw 3cosx" or something similar where they want you to show that you know that the max/min y value just became 3 instead of 1.

They need only identify horizontal and vertical asymptotes. Reply Link to post Share on other sites More sharing options...
