The moment generating function (mgf) of y is given by

Since the momoent generating function of x is given by

When p tends to 0, we have

Applying L'Hopital's rule we have:

This shows that y converges to <span>a chi squared random variable with 2r degrees of freedom</span>.
Answer:
the quotient is another word for division so the quotient in this equation is:
2x − 3 x ÷ 7 x2
y - 3x = 7
can be written as
y = 3x + 7
For every value of x there is a unique value of y. For example when x = 0 y = 3(0) + 7 = 7
Yes it is a function.
In particular it is a one-to-one function.
