To find the x intercept set y = 0
x^2 + x  - 2 =0 
(x+2)(x-1) = 0
x = -2 , x = 1
        
                    
             
        
        
        
Quadratic functions are second-order equations of the form y=ax^2+bx+c.  Their graphs form parabolas. The defining characteristic of a quadratic is that the acceleration of the outputs is a constant.

To solve this, we'll use Euler's Polyhedral formula.
This formula states that in any polyhedron, the number of vertices V, faces F, and edges E, satisfy:

If we solve for the edges E, we'll get:

Using the data given,

We get that the polyhedron would have 12 edges
