Answer:
sorry I don't know the answer
The rule for the translation is like a function. If X=2 and Y=-1, we just substitute those values in the rule of (x,y) => (x-1, y+3)
(2,-1)=>(1, 2) are the new coordinates. You went 1 to the left on the X axis and 3 up on the Y axis.
I assume
otherwise. If
is indeed a proper PDF, then its integral over the support of
is 1.

Compute the integral.

Then

Answer:
The answer will be <u>( n - 4 ) ( 3n² + 2 ).</u>
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.

2) Factor out the common term n - 4.

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>( n - 4 ) ( 3n² + 2 ).</u>
