 Hi and welcome to the session. Let's discuss the following question. The question says in each of the following exercises one, two, six, find the coordinates of the focus, axis of the parabola, the equation of the direct tricks, and the length of the latest rate term. Given equation of parabola is x squared equals to minus nine five. Let's now begin with the solution. Given equation of parabola is x squared equals to minus nine y. We know that if the equation of parabola has an x squared term, then the axis of symmetry is along y axis. Now here the equation of parabola contains x squared term, so the axis of symmetry is y axis. We also know that if the coefficient of y is negative then the parabola opens downwards. Now here coefficient of y is negative the parabola opens downwards. So in this case we have a parabola similar to this figure. Now x squared equals to minus nine y can be written as x squared equals to minus four into nine by four into y. Now this equation is of the form x squared equals to minus four a y. So comparing x squared equals to minus four into nine by four into y with x squared equals to minus four a y we get a as nine by four. We have learned that if the equation of parabola is of the form x squared equals to minus four a y then its focus is at the point zero minus a and direct trig is five equals to a. So this means focus of the parabola x squared equals to minus nine y is minus nine by four. Its equation of direct trig i equals to nine by four. Now we will find length of latest rectum. We know that length of latest rectum is four a and substituting value of a we get four into minus nine by four and this is equal to sorry four into nine by four we get nine. So length of latest rectum is nine. So the focus of the parabola is at the point zero minus nine by four axis of symmetry is y axis. Equation of direct trig of given parabola is y equals to nine by four and length of latest rectum of given parabola is nine. This is our required answer. So this completes the session. Bye and take care.
