not sure where to place this so random looks like a good place.

my teacher assigned homework over the weekend without explaining a few questions that i havnt seen. for example

given f(x) find each value  
f(3) if f(x) = 10x + 3x^2

i dont expect/want anyone to just give me the answer, but id like to know how to solve it.
