Answer: The value of polynomial function at -1 is 0 and the option d is correct.
Explanation:
The given function is,
We have to value of polynomial function at -1. It means we have to find f(-1).
Put x=-1 in the given function.
Therefore option d is correct and the value of polynomial function at -1 is 0.

Answer:
Step-by-step explanation:
Several trig identities are involved in the proof of this. This is the order in which they are used.
- cos(2x) = cos²(x) -sin²(x)
- cos²(x) +sin²(x) = 1
- cos(x) = 1/sec(x)
<h3>Proof</h3>
Starting with the left side, we can transform it into the right side.

Step-by-step explanation:
<u>Probability of getting heads</u>
- Outcome (head) = 1
- Total outcomes = 2
- P (head) = <u>1/2</u>
<u></u>
<u>Probability of getting an odd number</u>
- Outcome (odd) = {1, 3, 5} = 3
- Total outcomes = 6
- P (odd) = 3/6 = <u>1/2</u>
<u></u>
The outcomes are equally likely because the probabiity of each outcome is the same.
