  • Differentiate a first-derivative relation to express d²y/dx² in terms of x and y.
  • Use the sign of d²y/dx² to identify a concave-down region in the xy-plane.

AP Calculus BC Fun 4 E Justify Conclusions About the Behavior of an Implicitly Defined Function Based on Evidence From Its Derivatives Questions question 1

Given the following differential equation .

Find the second derivative, d2ydx2\frac{d^{2} y}{d x^{2}}, in terms of x and y. The region in the x y-plane where all the solution curves to the differential equation are concave down can be expressed as a linear inequality.

Find this region.
