sketch the graphs

Recommended Posts

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!

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.

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.

The definition of sketching a graph is that given in the Maths Studies Guide for first exams in 2006, which also gives details of the functions that students are expected to be able to graph. They need only identify horizontal and vertical asymptotes.
