Odd (second option)

Step-by-step explanation:

Plug -x in for x, and then simplify.

If it ends up same function then it is even.

If it ends up opposite then odd

So f(x) = -x / (x^2 - 1)

Plug in x = - x

f(x) = -(-x) / ((-x)^2  -1)

f(x) = x / (x^2 - 1)

This function is opposite the original function so answer is odd

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
