f(x)=7x^3+13x^3-3x^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^3-3x^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?
