By "slope" I assume you mean slope of the tangent line to the parabola.
For any given value of <em>x</em>, the slope of the tangent to the parabola is equal to the derivative of <em>y</em> :
The slope at <em>x</em> = 1 is 5:
The slope at <em>x</em> = -1 is -11:
We can already solve for <em>a</em> and <em>b</em> :
Finally, the parabola passes through the point (2, 18); that is, the quadratic takes on a value of 18 when <em>x</em> = 2:
So the parabola has equation

Answer:
12 sides
Step-by-step explanation:
Given
Sum of interior angle = 1800 degrees
Required
Number of sides of the polygon
The sum of interior of a convex polygon is calculated using the following formula:
Sum = (n - 2) * 180
Where n is the number of sides of the polygon.
By substituting 1800 for Sum, we have
Divide through by 180
Add 2 to both sides
Re order
Hence, the number of sides of the polygon is 12
