In (y=(x+2)^3-1), where does the point ((0,0)) of (y=x^3) move?

Answer and explanation

Correct answer: ((-2,-1))

The direct answer is A, \((-2,-1)\). Start with the parent graph \(y=x^3\), which contains the point \((0,0)\). In \(y=f(x+2)-1\), replacing x by \(x+2
displays the graph 2 units left, while subtracting 1 outside the function moves it 1 unit down. Therefore \((0,0)\) becomes \((-2,-1)\). Option A matches both movements. Option B, \((2,-1)\), moves right instead of left. Option C, \((-2,1)\), moves up instead of down. Option D has unrelated coordinates and represents neither required translation. Memory cue: plus inside means left; minus outside means down.
