Below are my Code to make the Object facing the Camera but I wanna Clamp the Object rotation min and max rotation to -45 degree and 45 degree

function Update () {

Here, check this for rotation clamp,

Also you can use transform.lookAt with lookrotation to look at object, i use this piece of code

public static void LookAtObject(Transform obj, float m_PopDistance)
    	{
    		transform.rotation = Quaternion.LookRotation (obj.forward);
    		transform.position = obj.position + obj.forward * m_PopDistance;
    		transform.LookAt(2 * transform.position - obj.position);
    	}
