Graph of a function | Wiskunde op Tilburg University

Introduction: One can draw the graph of a Function of one variable.

Definition: The graph of a function

$y$ with independent variable

$x$ is a figure in a coordinate system with two axes, the

$x$ -axis and the

$y$ - axis, consisting of the points with coordinates

$(x,y(x))$ .

Remark: It is convention to put the independent variable

$x$ on the horizontal axis and the dependent variable

$y$ on the vertical axis.

Example: The graph of

$N(t)=2t+3$ looks as follows.
