Cross section is a surface that is exposed after slicing or making a cut through an object. If a hexagonal pyramid is cut horizontally then the cross section should be an hexagon as well since the base is a hexagon. However, when it is cut vertically the resulting shape would be a triangle.
F(x) = 3x + 5/2
f(a+2) = 3(a+2) + 5/2 = 3a+6 + 5/2
= 3a + (12+5)/2 = 3a + 17/2
