Answer:

Refer the attached figure.    

Step-by-step explanation:

Given : Equations  [tex]y=x^3[/tex] and  [tex]y=\frac{16}{x}[/tex]

To find : Graph both the equations and Use the graphs to find the exact solutions to the equation [tex]x^3=\frac{16}{x}[/tex]

Solution :

Let, [tex]y=x^3[/tex] ........[1]

[tex]y=\frac{16}{x}[/tex]  .......[2]

Now, we plot these two equations.

The graph of  [tex]y=x^3[/tex]  is shown with green line.

The graph of [tex]y=\frac{16}{x}[/tex]  is shown with violet line.

Now, using the graph,

The solution to this system will be their intersection point.  

The intersection points are (2,8) and (-2,-8).

If we substitute y from [1] equation into [2]

We get, [tex]x^3=\frac{16}{x}[/tex]

Answer:

This is the same as the first answer but you can copy and paste this one :)
