Given y = xy + x^2 +1, first find y = f(x) = (x^2 + 1) / (1 - x). Then use the quotient rule for derivatives.
dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.
        
                    
             
        
        
        
9. In two years it would be (2,20) find the point on the grid and mark the spot.
In three years it would be (3,40) also mark that spot on the grid.
In four years it would be (4,80) mark this point on the grid 
All I'm doing is finding the number of the year and going up till it meets the red line or population amount.
Hope this helped you a little.
