There are a few math questions about Algebra. Please solve them before Wednesday. 1. Find the vertex, line of symmetry, and min or max for the function: f(x) =-(x+1) ^2-2 Find the vertex, line of symmetry, and min or max for the function: f(x) =-5(x+2) ^2+3 Find the vertex, line of symmetry, and min or max for the function: f(x) =9-x^2 Find the vertex, line of symmetry and min and max for the function: f(x) =-2x^2+2x+5 Find the x and y intercepts for the function: f(x) =16x^2+24x+9 Find the vertex, line of symmetry, and min or max f(x) =-x^2+2x+3 2. A farmer decides to enclose a rectangular garden, using the side of a barn as one side of the rectangle. What is the max area that the farmer can enclose with 60ft of the fence? What should the dimensions of the garden be to give this area? 3. Give exact and approximate solutions to three decimal places. x^2-7x+7=0 Give exact and approximate solutions to three decimal places. y^2-6y+9=100 Give exact and approximate solutions to three decimal places. (x-4)^2=4 4. Figure out the c value: E=jc^2 Figure out the x value: 2x^2=14 Figure out the x value: 3x^2-7x-13=0 5. Find the vertex and line of symmetry. f(x)=2(x-2)^2 Find the vertex and line of symmetry. f(x)=-1/2x^2 6. Find the x intercepts for the function: f(x)=2x^2-14 Find the x intercepts for the function: f(x)=3x^2-7x-13 7. Determine the nature of solutions of the equation. x^2-17=0 Determine the nature of the solutions of the equation. y^2=5/8y+3/5 8. The width of a rectangle is 5ft less than the length. The area is 6ft^2. Find the length and the width. 9. Write a quadratic equation in the variable x having the given numbers as solutions. Type the equation in standard form, ax^2+bx+c=0 10. Solve by completing the square. x^2+2x-8=0 http://www.bidanswer.com/Questions/QuestionInfo_10530.html
