0 Find the coordinates of the points on the curve f(x) = 2x - x2 + 6 where the tangents are parallel to the line -5x + 2y = 12. Hence, find the equation of the tangents at these points. 1 Find the equation of the tangent to the curve f(x) = 2x2 - 4x + 4 that is perpendicular to the line y = 1x+4. 2 WE15 Find the coordinates of the points where the tangents to the curve f(x) = x - 3x - 1 are perpendicular to the line x + 3y = 3. Hence, find the equations of the normals at these points
