f(x)=7x^3+13x^33x^2. Find f(6)
Also how do you solve this kind of question

notice that in the place of x in f(x) you now find a 6
so in the expression , replace x with 6 as well
f(x) = 7x^3+13x^33x^2
f(6) = 7(6)^3 + 13(6)^3  3(6)^2
= ...
I suspect a typo, why would you have two different cubic terms ?

So for this kind of question. You just replace the variables right?
