Answer:

Probability distribution B

Step-by-step explanation:

Probabilities cannot be negative numbers.  This means we can exclude distributions A and C.

Probability can be a maximum of 1.0.  This means we can eliminate distribution D.  

This leaves distribution B.

We can double check by finding the sum of the distribution.  The sum of a probability distribution is 1.0.  Adding these probabilities together, we have

0+0.45+0.16+0.39 = 1.00

B is correct.

Functions f(x) and g(x) are shown below:

Maximum value is found by solving the root of the first derivative. that root is where the maximum value is. 

f ' (x) = -8(x - 6) = 0. 

So x = 6 and that's the maximum value. f(6) = 3 

2cos(2x - π) + 4 is a trig function. The maximum value of cosine function is 1. 

So the maximum value would be 2(1) + 4 = 6.
