For the function f (x) = (x - 2) 2 + 4, identify the vertex, domain, and range.

The vertex form of a quadratic function is given by f (x) = (x - h) ^2 + k, where (h, k) is the vertex of the function. Hence, for the given function, vertex = (2, 4)

Domain is all real numbers and range is {f (x) : f (x) > = 4}
