At what point on the parabola y = 3 x 2 + 2x is the tangent line parallel to the line y = 10x − 2? Use first principles in your solution
Your equation doesn't unambiguously look like the equation of a parabola (is it 3x^2 + 2x ?) and I don't know what 'first principles' means in the context of the question. That said, what is the gradient of the straight line, how do work out the gradient of a curve at any point?
