The curve \(C\) has equation

\(y=\frac{{{x}^{2}}+3x-1}{x-2}\), \(x\in \mathbb{R}\), \(x\ne 2\).

  1. Using an algebraic method, find the range of values that \(y\) can take.[4]
  2. Sketch \(C\), stating the equations of the asymptotes, axial intercepts and the coordinates of the turning points, if any.[4]
  3. State the range of values that \(m\) can take such that the equation \(\frac{{{x}^{2}}+3x-1}{x-2}=m\left( x-2 \right)+7\) has \(2\) distinct solutions, justifying your answer.[2]
