1. f(x)=-x^2+2x+3 and g(x)=x+1 on the interval [-1,2] 2. using the left hand rectangular approximation method with 5 equal subintervals find the area under the curve f(x)=?1+x^3 on the interval [0,1]

from the function f(x)=x/x^2+9 1) How can I show that x=-3 is a critical point 2) Use 2nd Derivative Test to show if -3 is a rel min or rel max
