Given that lim x>c f(x)=6 and that lim x>c g(x)= 4, evaluate the following limit. Assume that c is a constant. The x in front of the f is confusing me.
lim [xf(x) + 3 g(x)]^2
x>c

The x in front of the f is any constant you would put in the equation.
Example: x>5 5=c
lim [xf(x) + 3 g(x)]^2
x>5
so, [5*6 + 5*(4)]^2
You should be able to do the rest.

[c*6 + 3*(4)]^2 = (6c 12)^2
= 36c^2  144c + 144
