f(x)=x-12
X=f(x)+12
f^-1(x)=x+12
Answer: The correct option is 1.
Explanation:
The given piecewise function is,

It means if x<0, then

If
, then

Since the f(x) is defined for x<0 and
, therefore the function f(x) is not defined for
.
From the graph 2, 3 and 4 we can easily noticed that for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for
, hence the first option is correct.
R<5
r has to be less than 5, now doesn't it
