Inverse of a function is also a function, if and only if the function is One - to - One. This means no y value occurs in the range of the function more than once.

If we observe the given options, we can see option B, C and D have some repeated values of y. Only the function in option A is one to one. Hence the inverse of function given in option A will also be a function.

So, the answer to this question is option A

Answer:

The right answer is "0.3193".

Step-by-step explanation:

According to the question,

Mean,

$\frac{1}{\lambda} = 13$

$\lambda = \frac{1}{13}$

As we know,

The cumulative distributive function will be:

⇒ $1-e^{-\lambda x}$

hence,

In the first 5 years, the probability of failure will be:

⇒ $P(X$

$=1-e^{-(\frac{1}{13} )\times 5}$

$=1-e^(-\frac{5}{13})$

$=1-0.6807$

$=0.3193$
