Question 353035: f(x)=8-x^2
I got
Vertex (0, x^2)
Line of Symmetry x=0
Max/Min -x^2
Value of, f(0)=8 max/min
I choose max.
What I cannot figure out is how do I graph this one?

You can put this solution on YOUR website!
f(x)=8-x^2
I got
Vertex ?
Vertex occurs when x = -b/(2a) = -0/(2*-1) = 0
f(0) = 8
Vertex is (0,8)
------------------------
Line of Symmetry x=0
Max/Min:: Max because the coefficient of x^2 is negative
Value of, f(0)=8 max
how do I graph this one?
Plot (0,8) and a couple points to the left and to
the right of x = 0
