I. Find the vertex and the axis of symmetry of the associated parabola for each quadratic function. Find the intervals on which each function is increasing and decreasing, and find the range. Axis of Increasing Decreasing Function Vertex Symmetry Interval Interval Range f(x) = x2 +8x+ 3 g(x) = -2x3 + 3x - 7 h(x) =0.6x2 - 2.4x + 1.3 f(x) =-x2 - 5x +8 g (x) =: OIN x2 + = x - 5 II. Word problems. 1. A farmer has 350 feet of fencing material to make two identical, adjacent rectangular corrals for the farm animals, as pictured below. If the farmer wants to maximize the total enclosed area, what will be the dimensions of each corral? y + X - 1+ X
