Given: <span>f(x) = log3 (x + 1), look for f^-1 (2)
We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:
</span><span>f^-1 (2) = 8</span>
Answer:
C. hyperbola; 
Step-by-step explanation:
The given conic has equation:

Divide through by 225.


This is a hyperbola centered at the origin.
The hyperbola has been translated from the origin to (0,5).
The translated hyperbola will have equation;

Multiply through by 225.

Expand


Rewrite in general form;


X=-2
5-4=1
so whatever is square rooted must be equal to 1
1 squared is 1
-2+3 is one
