A space traveler is moving from left to right along the curve When she shuts off the engines, she will continue traveling along the tangent line at the point where she is at that time. At what point
$(x,y)= ($ , $)$
should she shut off the engines in order to reach the point $(4,15)$?
If she was traveling from right to left she would have to shut off the engines at the point $(x,y)= ($ , $)$.
