So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.
A is the answer 1/3 and 1/3 are the same
Since y is the suqraed term, it opens left or right
in this form it is
(y-k)²=4p(x-h)
(h,k) is the vertex
if p is negative then it opens to the left and directix is to the right of the vertex
if p is positve then it opens to the right and directix is to the left of the vertex
p is the distance from vertex to directix
so
(y-0)²=4(-6)(x-0)
the vertex is (0,0)
-6 is negative
so
vertex is (0,0)
directix is 6 unts to the right of (0,0) or at x=6
the directix is x=6
