A linear function is a polynomial function of degree 1 (1,2,3,4,5,6,....) A quadratic function is a polynomial function of degree 2 (1,4,9,16,25,49,64,81,...) A exponential function is not a polynomial function (we may imagine a infinity degree) (1,2,4,8,16,32,64,128,256,512,1024,...)
Leading Question is the type of question that implicitly encourages a respondent to answer in a particular way. Leading questions are generally inappropriate as they lead to false and slanted information.
for example: If you ask an employee that "Do you have any Problem with your boss?"
This questions explicitly encourages the employee to think that there are Problems.
Another example is that
"How fast is truck moving when it crashed into the car?"
This question directly blames the truck that it is at fault.
Similarly, the above question indicates that all Americans must possess cell phones
