Answer:
A. Yes, the table shows a probability distribution.
Step-by-step explanation:
In a probability distribution, none of the values can be negative or over 1. Additionally, all of the values must sum to 1.
Our probabilities are:
0.087; 0.328; 0.416; and 0.169. None of these are negative and none are over 1.
0.087+0.328+0.416+0.169 = 1.00; this means that this is a probability distribution.
If f (x) =- 4x2 +15, then f (-3) = -21
