The sum of the interior angles of the polygon = (n - 2) x 180 .

(n - 2) x 180 = (n x 150)

180n - 360 = 150n

Add 360 to each side:

180n = 150n + 360

Subtract 150n from each side:

30n = 360

Divide each side by 30 :

<u>n = 12</u>

The graph of a function f crosses the x-axis at -1 and 3 and touches the x-axis at 5. Which equations could define this function
sattari [20]

Given:

The points where the graph crosses the <em>x</em>-axis are -1 and 3.

The point where the graph touches the <em>x</em>-axis is at 5.

The objective is to find the correct equation of the function.

Explanation:

The equation representing the point <em>x</em> = -1, crossing the <em>x</em>-axis can be represented as,

\begin{gathered} x=-1 \\ (x+1)=0_{} \end{gathered}

Similarly, the equation representing the point <em>x</em> = 3, crossing the <em>x</em>-axis can be represented as,

\begin{gathered} x=3 \\ (x-3)=0 \end{gathered}

Similarly, the equation representing the point <em>x</em> = 5, touching the <em>x</em>-axis can be represented as,

\begin{gathered} x=5,x=5 \\ (x-5)(x-5)=0 \\ (x-5)^2=0 \end{gathered}

By combining all the equations of the graph, the function can be represented as,

f(x)=(x+1)(x-3)(x-5)^2

Hence, option (B) is the correct answer.
