What is the vertex of the graph of the function \(f(x)=(x+2)^2\)?

Answer and explanation

Correct answer: \((-2,0)\)

The function is in vertex form \(y=(x-h)^2+k\), where \(h=-2\) and \(k=0\). Thus, its graph is \(y=x^2\) shifted 2 units to the left, giving the vertex \((-2,0)\). Option A has the wrong sign for the x-coordinate. Exam tip: the vertex of \((x+a)^2\) is \((-a,0)\).
