Answer:
x=60
Step-by-step explanation:
since f(x) =60 then y is f(x) and in the form y=x 60 is x
Solving for the missing variable
I think it is not possible to find a certain equation from just a given points, it must have more given information because there is a lot of parabola pass throw (-1,1).
F ( x ) = 6^(x+1)
y = 6^(x+1)

The inverse is:

And when you plug in the values: x = 1, y = - 1:
- 1 = log 1 - 1
- 1 = 0 - 1
- 1 = - 1
so the answer is:
( 1, - 1 )
