1/4 = & + /(*) is the F graph displaced along Uve (/-axis by an amount<br />

(Fg. 3).<br />

Example. Construct the graph of the function<br />

Solution. The desired l<strong>in</strong>e is a s<strong>in</strong>e curve y = s<strong>in</strong>x displaced along the *-axis<br />

to the right by an amount -j (Fig. 4)<br />
