What is the inverse of the function f(x)=3cube
1 answer:
Answer:
Inverse does not exist.
Step-by-step explanation:
Given is a function
We are asked to find an inverse for this function.
On analysing the function, we find that for all values of x,
y is a constant.
In other words, this is nothing but a constant function which is a horizontal line parallel to x axis.
This is not onto, because range of this funciton is only the value {3^3}
Inverse exists only for one to one and onto funcitons.
Since this function is one to one but not onto, inverse does not exist.

We are supposed to find mean and standard deviation
Mean =
Standard deviation =
