Question

write each quadratic function in vertex for. Find the coordinates of the vertex and the equation of the axis of symmetry.

f(x) = -1/2x^2

Answer 1

the axis of symmetry is \(\huge \frac{-b}{2a}\) where \(\large ax^2+bx+c\). Here b is 0 so we have an axis of symmetry of \(\huge \frac{-0}{2*\frac{-1}{2}}= \frac{0}{-1}\) or just 0

a look at the graph confirms this

Answer 2

similarly the vertex would be (0,0)
