If (f(x)=|x-2|+3), what is the vertex of its graph?

Answer and explanation

Correct answer: ( (2,3) )

The direct answer is A, \((2,3)\). The basic graph \(y=|x|\) has its vertex at \((0,0)\). In \(y=|x-2|+3\), replacing x by x−2 shifts the graph 2 units right, and adding 3 outside shifts it 3 units up. Therefore the vertex becomes \((2,3)\). Equivalently, the absolute value is smallest when x−2=0, so x=2; then y=|0|+3=3. Option A is correct. Option B, \((-2,3)\), would result from \(|x+2|+3\), a left shift. Option C, \((3,2)\), reverses the coordinate roles. Option D, \((0,3)\), ignores the horizontal shift. Memory cue: in \(|x-h|+k\), the vertex is \((h,k)\), and the graph is a V opening upward.
