Answer:
Step-by-step explanation:
To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.
If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.
So
We also know that:
Since the express train travels 3 times faster than the freight train.
So, like both equations, we have to:
Then miles in the opposite direction.
This is the distance you traveled in 15 minutes.
Therefore, the speed of the express train () is the distance traveled between the time it did
equation is:
so if its even f(-x) should be equal to f(x)
that means
so f(x) is not equal to f(-x) so its not even
If its odd than f(-x) should be equal to -f(x)
so as we can see f(-x)= - f(x)
so the function is odd
Ans:function is odd and not even
