Answer:
Step-by-step explanation:
By definition the domain of an inverse function is the range of f(x) and the range of the inverse function is equal to the domain of the principal function f(x).
If you have a function , then to find the inverse function, follow these steps:
1. Make
2. Solve for the variable "x":
3. Exchange the variable "x" with the variable "y":
4. Exchange "y" with. Then the inverse function is:
Answer:
see attached
Step-by-step explanation:
The equation is in the form ...
4p(y -k) = (x -h)^2 . . . . . (h, k) is the vertex; p is the focus-vertex distance
Comparing this to your equation, we see ...
p = 4, (h, k) = (3, 4)
p > 0, so the parabola opens upward. The vertex is on the axis of symmetry. That axis has the equation x=x-coordinate of vertex. This tells you ...
vertex: (3, 4)
axis of symmetry: x = 3
focus: (3, 8) . . . . . 4 units up from vertex
directrix: y = 0 . . . horizontal line 4 units down from vertex
