Take the largest exponent in the function and you've got the order

Explanation:

Let's say for example we have the function
#y=5x^3+2x^2+10x+1#

This equation's highest exponent is 3, so it is of the third order.

It gets trickier when it is under parentheses or not fully expanded, take the following equation as an example:

#y=(x^2+4)^2#

To tackle these ones, expansion is needed. In this case the highest exponent will come from the #x^2# multiplied by itself to get #x^4#. So the above equation would be of the fourth order.

Hope that helps!
