Graph y = x 3 and y = 16/x on the same set of coordinate axes. Use the graphs to find the exact solutions to the equation x 3 = 16/x . Verify by substitution that they satisfy the equation.

Verified Answer :

Answer:

Refer the attached figure.    

Step-by-step explanation:

Given : Equations  \(y=x^3\) and  \(y=\frac{16}{x}\)

To find : Graph both the equations and Use the graphs to find the exact solutions to the equation \(x^3=\frac{16}{x}\)

Solution :

Let, \(y=x^3\) ........[1]

\(y=\frac{16}{x}\)  .......[2]

Now, we plot these two equations.

The graph of  \(y=x^3\)  is shown with green line.

The graph of \(y=\frac{16}{x}\)  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, \(x^3=\frac{16}{x}\)
