Answer:
The inverse function is 
Step-by-step explanation:
The given function is 
.
This function is only invertible on the interval, 
.
To find the inverse on this interval, we interchange 
and 
.
We now make the subject to get,
But the given interval is 
, This implies that, 
.
Answer:
(a) and (e) are not valid.
Step-by-step explanation:
a) The number of traials is not fixed. In fact, the random variable counts the total number of trials.
b) This is true, the result of each trial is independent of the others.
c) This is also true. The outcomes are failure and success.
d) This is true as well, all trials are identically distributed.
e) Since (a) is not valid, this cant be true.

Answer:
C)
f(–3) = 9
Step-by-step explanation:
Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45
f(-3) means let x = -3
f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45
=4(81) +5(-27) -15(9) -45
= 324 - 135 - 135 -45
=9
