1 Test Review Section.. Given the following function: f ( ) = Determine the implied domain of the given function. Epress your answer in interval notation.. Find the verte of the following quadratic function. Reduce all fractions to the lowest terms. g ( ) = Among all pairs of numbers ( y) such that 8 + y =, find the pair for which the sum of squares, + y, is minimum. Reduce all fractions to the lowest terms.. A rancher has 800 feet of fencing to put around a rectangular field and then subdivide the field into identical smaller rectangular plots by placing a fence parallel to one of the field's shorter sides. Find the dimensions that maimize the enclosed area. Reduce all fractions to the lowest terms. 5. The back of Tom's property is a creek. Tom would like to enclose a rectangular area, using the creek as one side and fencing for the other three sides, to create a pasture. If there is 90 feet of fencing available, what is the maimum possible area of the pasture? Section. 6. Consider the following piecewise-defined function. f() = 5 Step. Evaluate the given function at = -. If the value is undefined, write "Undefined". Step. Evaluate the given function at = -7. If the value is undefined, write "Undefined". Step.
