Which graph best represents the quadratic function f(x)=x2−4x+3f(x) = x^2 - 4x + 3?

  1. Graph AGraph A: an upward-opening parabola with its vertex at 2, negative 1, crossing the x-axis at 1 and 3 and the y-axis at 3.
  2. Graph BGraph B: an upward-opening parabola with its vertex at 1, 2, crossing the y-axis at 3.
  3. Graph CGraph C: an upward-opening parabola with its vertex at negative 2, negative 1, crossing the x-axis at negative 3 and negative 1 and the y-axis at 3.
  4. Graph DGraph D: an upward-opening parabola with its vertex at negative 1, 2, crossing the y-axis at 3.

1. Understand the question

Find the vertex of f(x)=x2−4x+3f(x) = x^2 - 4x + 3, then match it to a graph.

Try the question on your own first, then reveal one step at a time.
