Find the vertex, line of symmetry, and the minimum or maximum value. f(x)=8-x^2
yeah never heard of that
rewrite in standard form f(x) = -x^2 + 8 line of symmetry: (x-coord of vertex) x = -b/2a If a is negative, parabola opens down --> maximum if a is positive,parabola opens up --> minimum
Ok. what do you mean in standard form? Like (2,8)?
standard form of a quadratic equation \[ax^{2} +bx+c \]
I guess I don't know how to do that.
