It's just a symbol, I think it stands for formula.Jenspm wrote:
What's "f"?
(we use different symbols here)

f of x - f(x)Jenspm wrote:

is basically just a function to be used on the variable x.

The question says to leave it in surd form:SplinterStrike wrote:
Basically, X is replaced by 12 in your equation.
So you'll have:
f(x)=3(sqrt)x
f(12)=3(sqrt)12
f(12)=3 X 2 X (sqrt)3
f(12)= 6 X 1.732
f(12)= 10.392
