(i) To find the values of \(k\) for which the line and curve meet at two distinct points, equate the equations:
\(3kx - 2k = x^2 - kx + 2\)
Rearrange to form a quadratic equation:
\(x^2 - 4kx + 2k + 2 = 0\)
For two distinct points, the discriminant \(b^2 - 4ac > 0\).
Here, \(a = 1\), \(b = -4k\), \(c = 2k + 2\).
Calculate the discriminant:
\((-4k)^2 - 4 \times 1 \times (2k + 2) > 0\)
\(16k^2 - 8k - 8 > 0\)
Factorize or solve the inequality:
\((k - 1)(k + \frac{1}{2}) > 0\)
Thus, \(k > 1\) or \(k < -\frac{1}{2}\).
(ii) For the line to be tangent to the curve, the discriminant must be zero:
\(16k^2 - 8k - 8 = 0\)
Solving gives \(k = 1\) and \(k = -\frac{1}{2}\).
For \(k = 1\), the line is \(y = 3x - 2\) and the curve is \(y = \frac{3}{2}x + 1\).
Equate the tangents:
\(3x - 2 = \frac{3}{2}x + 1\)
Solve for \(x\):
\(x = \frac{2}{3}\)
Thus, the tangents meet on the x-axis at \(x = \frac{2}{3}\).
