... orienting the large rectangle so that the lower-left corner is a lattice point. A lattice point (m, n) on the plane is one having integer coordinates. Next, we make the following key observation: If the rectangle weren’t good, then it would have only one lattice point corner. But if the rectangle is ...

... Explanation The x values of points of inflection on f(x) exist where f’’(x) = 0. When f(x) = (x3+2)(x4) or x7 +2x4, f’(x) = 7x6 + 8x3. So, f’’(x) = 42x5 + 24x2 Using a graphing calculator find where f’’(x) = 0. For 0 = 42x5 + 24x2, x = -0.830. Now, substituting .83 into the original equation, we fi ...
