Question 1064208

   Given the quadratic function f(x) = -2x2 - 12x - 10
 a. Use “completing the squares” to convert the quadratic function into vertex form 
b. State the vertex 
c. Find the x- and y-intercepts 
d. Graph the function 
<pre>Correct answer: Equation is: {{{y = - 2(x + 3)^2 + 8}}}, after completing the square, so: {{{highlight_green(matrix(1,3, "Vertex", "=", "(- 3, 8)"))}}}
After using a method your choice, you should get: {{{highlight_green(matrix(1,3, matrix(1,2, "y-intercept:", "(0, - 10)"), and, matrix(1,4, "x-intercepts:", "(- 5, 0)", and, "(- 1, 0)")))}}}
