Question 981541: 1.)F(x)= 2/x+4 -4
How do i find the x intercepts, y coodinates, equation for the axis of symetry, range and domain of the function?
2.)g(x)= -2x^2 +4x-6
rewrite the equation in the form g(x)=a(x-p)^2 +q and give the axis of symetry and x-intercepts

You can put this solution on YOUR website!
1.)
F(x)= 2/x+4 -4
WHAT?


2.)
g(x)= -2x^2 +4x-6
g%28x%29=+-2x%5E2+%2B4x-6

Complete The Square.
-2%28x%5E2-2x%2B3%29
-2%28x%5E2-2x%2B1-1%2B3%29-------See the lesson why 1 is chosen.
-2%28%28x%5E2-2x%2B1%29-1%2B3%29
-2%28%28x-1%29%5E2%2B2%29
highlight%28g%28x%29=-2%28x-1%29%5E2-4%29
Solve this for g%28x%29=0 to find the zeros. You will NOT need to remultiply the square binomial in order to do this; doing so would take you away from the use of Completing The Square that was done.

Read the vertex directly from the standard form equation or function.
Vertex is (1,-4).
