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.

what is the approximate percent increase when the population of a town increases from 12089 to 15025? round the amounts to the n

bulgar [2K]

The rate of increase is
$\frac{15025}{12089}\approx1.242865$

The percent of increase is then
$(1.242865-1)*100\%=0.242865*100\%=24.2865\%$
