There are no jumps or holes in the graph of a polynomial function. </li> <li>A smooth curve means that there are <strong>no sharp turns</strong> (like an absolute value) in the graph of the function.</li> <li>The <strong>y-intercept</strong> of the polynomial is <strong>the constant</strong> term a<sub>0</sub>.</li> </ul> <h3>Leading Coefficient Test (right hand behavior)</h3> <ul> <li>If the leading coefficient, a<sub>n</sub>, of the polynomial is <strong>positive</strong>, then the right hand side of the graph will <strong>rise</strong> towards + infinity. </li> <li>If the leading coefficient, a<sub>n</sub>, of the polynomial is <strong>negative</strong>, then the right hand side of the graph will <strong>fall</strong> towards - infinity.</li> </ul> <h3>Degree of the Polynomial (left hand behavior)</h3> <ul> <li>If the degree, n, of the polynomial is <strong>even</strong>, the left hand side will do the <strong>same</strong> as the right hand side.</li> <li>If the degree, n, of the polynomial is <strong>odd</strong>, the left hand side will do the <strong>opposite</strong> of the right hand side.</li> </ul> <p>Get used to this even-same, odd-changes notion.
