 Quadratic_Equations/352607: Find the vertex, the line of symmetry, the maxiumum or minimum value of the quadratic function, and graph the function. f(x)=-2x^2+2x+3 The x-coordinate of the vertex is: The y-coordinate of the vertex is: The equation of the line of symmetry is x= The maximum/minimum of f(x) is: The value, f(1/2)=7/2 is minimum or maximum? So far, I have tried to work the problem. This is what I have: f(x)=-2x^2+2x+3, so you use (-b/2a,4ac-b^2/4a) Therefore, if -b/2a=-(2)/2(-1)=1 Then put 1 back into the equation. f(1)=-2(1)^2+2(1)+3 Using FOIL, I come up with 1. This where I get confused. Is the x-coordinate 1? How do i come up with y-coordinate? Is the line of symmetry also 1? I think I confuse myself the most when I try to apply the FOIL method? Any help is so very much appreciated!
