I'm guessing you're given the function , and you're asked to find the inverse function
. To do this, swap
and
, then solve for
:
so that the inverse function is
Just to verify:
But in case you're actually only interested in computing the square root, first we note that (the real-valued square root) is only defined as long as
. So
is defined as long as
, or
, or equivalently
. Under this condition, we could write
We can simplify this further, but we have to be careful. Suppose . Then
. But we get the same result if
, since
. There are two possible values of
that given the same value of
, so to capture both of them, we take
, the absolute value of
. Then
We can't simplify the square root term further than this.
Answer:
Here is the representation of a histogram. This represents in a continuous distribution the probability frequency of the books that Pedro had read in the summer.
Know that the probability frequency is:
