Consider the parabola given by the equation: y= r + 2x - 8 Does the graph open up or down? Does the graph have a maximum or a minimum? Oopens down, maximum Oopens up, maximum Oopens up, minimum Oopens down, minimum The vertex is The y-intercept is (0,Consider the Quadratic function f(x) = 4x - 25. Its vertex is Preview Preview ). Its largest r-intercept is r = Preview Its y-intercept is y = PreviewConsider the Quadratic function f() = C - 70 - 8. Its vertex is Its largest -intercept is r = Its y-intercept is y =Consider the quadratic function f(x) = - 21 - 2x + 12. Determine the following: (enter all numerical answers as integers, fractions, or decimals): The smallest r-intercept is = = The largest r-intercept is r = The y-intercept is y = The vertex is ( The line of symmetry has the equationConsider the parabola given by the equation: + 2x + 1 Find the following for this parabola: A) The vertex = B) The y intercept is the point (0, C) Find the two values of a that correspond to the r intercepts of the parabola and write them as a list, separated by commas: Round your answer(s) to two decimal places. After you do your calculations, you should practice sketching the parabola accurately on paper.Manuel wants to build a rectangular pen for his animals. One side of the pen will be against the barn; the other three sides will be enclosed with wire fencing. If Manuel has 550 feet of fencing, what dimensions would maximize the area of the pen? a) Let w be the length of the pen perpendicular to the barn. Write an equation to model the area of the pen in terms of w Area = Preview b) What width w would maximize the area? 7= PreviewThe cost C (in dollars) for a company to produce and sell a thousand gadgets is given by C : 1 20 x - 2x + 3020 (a) What is the company's start-up cost?
