F(x)= -8x²
f(-3)= -8* (-3)²
f(-3)= -8 * 9
f(-3)= -72

Total number of seats = 5
Total number of friends = 5
We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.
5P5 = 120
So, the 5 friends can sit in 120 different ways.
The correct answer is option D
Answer:
A path that goes through every EDGE once and starts and ends at different vertices.
Explanation:
A "Euler path" is a trail that is being used in a graph consisting of finite number of edges. It is also known as "Eulerian path." This should be contrasted from the "Euler circuit," for both of their meanings are a bit confusing.
A Euler path only uses every edge of the graph once and it starts and ends at<em> different vertice</em>s. A Euler circuit, on the other hand, uses every edge of the graph exactly once but <em>starts and ends at the same vertex</em>.
So, this explains the answer.
