Identify the graph of the equation. what is the angle of rotation for the equation?

2xy – 9 = 0

b. hyperbola,

Step-by-step explanation:

The given equation is;

Comparing to the general equation;

,

We can eliminate the xy term using;

This implies that;

Substitute into the original equation;

This is a hyperbola;

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
