I already drew the graph!

Algebra Level 3

How many of the given functions below can have the graph shown in the image?

Details: \((h,k)\) is the minimum point of the graph

  1. \(f(x) = x^3 + 3x\)

  2. \(f(x) = 2x^2 - 3x + 5\)

  3. \(f(x) = x^2 - 4x -5\)

  4. \(f(x) = x^2 + 4x - 5\)

  5. \(f(x) = 3 -2x\)

  6. \(f(x) = 4x^2 - 8x - 21\)

  7. \(f(x) = 4 - 3x - x^2\)
