the attachment shows my work. I honestly think maybe i did something wrong. at any rate the integrand is 1 and so not really even or odd.
any help is appreciated

So would be <p> =∫ψ*(x)P(hat)ψ(x)dx
P(hat) = -ih(bar)(d/dx)

Linear momentum is a physical quantity that describes the motion of a particle in a straight line. It is defined as the product of an object's mass and its velocity.
Linear momentum is calculated by multiplying the mass of an object by its velocity. The formula for linear momentum is p = mv, where p is momentum, m is mass, and v is velocity.
The units of linear momentum are kilogram-meters per second (kg*m/s) in the SI system, and gram-centimeters per second (g*cm/s) in the CGS system.
Yes, according to the law of conservation of momentum, the total linear momentum of a closed system remains constant, as long as there are no external forces acting on the system. This means that the total momentum before an event is equal to the total momentum after the event.
Linear momentum is closely related to other physical quantities, such as force and acceleration. It is directly proportional to force, and is equal to the product of mass and acceleration. It is also related to kinetic energy, as the change in an object's momentum is equal to the force acting on it multiplied by the distance it travels, which is the definition of work and, therefore, kinetic energy.
