As in the previous question, let ƒ, g: [−1, 1] and define a smooth curve y: [-1, 1] → R² by y(t) = (f(t), g(t)). Which of the following statements about the regularity of y are true? Select one or more: R be smooth strictly increasing functions, a. For any such f and g, y is regular. b. If f and g both have critical points then y is not regular. C. If one of the functions for g has a critical point, then y is not regular. d. If both f and g have no critical points then y is regular. e. If one of the functions for g has no critical points, then y is regular. y is regular if and only if both of the functions f and g have no critical points. g. y is regular if and only if one of the functions for g has no critical points.
