Question

How do you find the axis of symmetry, graph and find the maximum or minimum value of the function `f(x) = 1/4(x-2)^2 -4`?

Answer 1

Axis of symmetry is x=2, minimum value -4, maximum value `oo`

Explanation:

All the required information can be read from the given equation it self. Given quadratic expression represents a vertical parabola opening up with its vertex at (2,-4), the axis of symmetry being x=2, The minimum value would be at its vertex , x=2. It would be -4 and the maximum value would be `oo`
