a)

To write: An equation that can be solved to find the points of intersection of the graphs of $y1$ and $y2$ .

An equation that can be solved to find the points of intersection of the graphs of $y1$ and $y2$ is $−x3−2x2+5x+2=0$

Given Information:

The equations $y1=4x+5$ , $y2=x3+2x2−x+3$ and $y3=−x3−2x2+5x+2$ .

Concept Used:

The points of intersection of graphs of $y1$ and $y2$ are the values of $x$ where $y1=y2$ .

Calculation:

Equate $y1=4x+5$ to $y2=x3+2x2−x+3$ and simplify.

$y1=y24x+5=x3+2x2−x+3x3+2x2−x+3−4x−5=0x3+2x2−5x−2=0−x3−2x2+5x+2=0$

Therefore, $−x3−2x2+5x+2=0$ is an equation that can be solved to find the points of intersection of the graphs of $y1$ and $y2$ .

b)

To find: Write an equation that can be solved to find the x -intercepts of the graph of y .

The required equation is $−x3−2x2+5x+2=0$ .

Given Information:

The equation $y3=−x3−2x2+5x+2$ .

Concept Used:

The intercept for any equation is found by equation it to 0.

Calculation:

Equate $y3$ to 0.

$y3=0−x3−2x2+5x+2=0$

Therefore, the required equation is $−x3−2x2+5x+2=0$ .

c)

To explain: How does the graphical model reflect the fact that the answers to (a) and (b) are equivalent algebraically.

Given Information:

The equations $y1=4x+5$ , $y2=x3+2x2−x+3$ , $y3=−x3−2x2+5x+2$ and the graph shown in figure 1.

Figure 1

Explanation:

Draw the vertical lines at the points of intersection of $y1$ and $y2$ as shown in figure 2.

Figure 2

From figure 2 it follows that the value of $x$ at which the graphs of $y1$ and $y2$ intersects are the $x$ -intercepts of the graph of $y3=−x3−2x2+5x+2$ .

Also, the equation for finding the intersection points of $y1$ and $y2$ is same equation that can be used to find the $x$ -intercepts $y3=−x3−2x2+5x+2$ .

Therefore, the graphical model reflects the fact that the answers to (a) and (b) are equivalent algebraically.

d)

To check: Numerically that the $x$ -intercepts of $y3=−x3−2x2+5x+2$ give the same values when substituted into the expressions for and $y1$ and $y2$ .

Given Information:

The equations $y1=4x+5$ , $y2=x3+2x2−x+3$ and $y3=−x3−2x2+5x+2$ .

Calculation:

The equation $−x3−2x2+5x+2=0$ gives the x -intercepts of the graph of $y3$ .

The graph of $−x3−2x2+5x+2$ is shown in figure 3.

Figure 3

Thus, the real solutions of $−x3−2x2+5x+2=0$ are $−3.323$ , $−0.358$ and $1.681$ .

Now, substitute $x=−3.323$ , $x=−0.358$ and $x=1.681$ into $y2=x3+2x2−x+3$ as follows.

$y1−3.323=4−3.323+5=−8.292y1−0.358=4−0.358+5=3.568y11.681=41.681+5=11.724$

Now, substitute $x=−3.323$ , $x=−0.358$ and $x=1.681$ into $y1=4x+5$ as follows. $y2−3.323=−3.3233+2−3.3232−−3.323+3=−8.286y2−0.358=−0.3583+2−0.3582−−0.358+3=−3.568y21.681=1.6813+21.6812−1.681+3=11.721$

Thus, $y1=y2$ at the points $−3.323$ , $−0.358$ and $1.681$ .

Therefore, it follows that the intercepts of $y3=−x3−2x2+5x+2$ aret the points of intersection of $y1$ and $y2$ .
