Q. 17 - Precalculus Enhanced with Graphing Utilities

Question

Sketch the graph of each function. Be sure to label three points on the graph.

$f\left(x\right)=x$.

Step-by-Step Solution

Answer

The graph is 

Step 1. Given information.

The given function is,

 $f\left(x\right)=x$.

Step 2. Finding the ordered pairs.

Using the point plotting method we get, 

$x$	$$\begin{gathered} y=f\left(x\right) \\ =x \end{gathered}$$	$\left(x,y\right)$
$-1$	$-1$	$\left(-1,-1\right)$
$0$	$0$	$\left(0,0\right)$
$1$	$1$	$\left(1,1\right)$

Step 3. Plotting the points on a graph.

The graph is
