To find the values of m for which the line and the curve intersect at two distinct points, we equate the equations:
\(3x^2 + 2x + 4 = mx + 1\)
Rearranging gives:
\(3x^2 + (2 - m)x + 3 = 0\)
For the line and the curve to intersect at two distinct points, the discriminant of this quadratic equation must be greater than zero:
\((2 - m)^2 - 4 imes 3 imes 3 > 0\)
\((2 - m)^2 - 36 > 0\)
\((2 - m)^2 > 36\)
Taking the square root of both sides:
\(|2 - m| > 6\)
This gives two inequalities:
\(2 - m > 6\) or \(2 - m < -6\)
Solving these inequalities:
1. \(2 - m > 6\) gives \(m < -4\)
2. \(2 - m < -6\) gives \(m > 8\)
Thus, the set of values of m for which the line and the curve intersect at two distinct points is:
\(m < -4\) or \(m > 8\)
