Now we will learn how to find the focus & directrix of a parabola from the equation. So, when the equation of a parabola is y – k = a (x – h) 2 Here, the value of a = 1/4C So the focus is (h, k + C), the vertex is (h, k) and the
Let me just say I got an A+ on my assignment, I just hope Premium gets canceled because it doesn't help knowing the answers but not the steps. Helped me sooo much through school. It can draw graphs, find variables and of course solve all the basics.
Find the focus of the parabola () = (). It’s another “regular” parabola, which means you use y = a ( x − h ) 2 + k {\displaystyle y=a(x-h)^{2}+k} and ( h , k + 1 / ( 4 a ) ) {\displaystyle
