QUESTION:

Suppose that **lim x-> c f(x) = L** where L >0, and that **lim x-> c g(x) = infinity**.

I want to show that lim x->c f(x)g(x) = infinity

MY SOLUTION

Using properties of limits theorem

let f,g be real functions , **lim x-> c f(x)g(x) = L x infinity**

where L x infinity = infinity

hence **lim x-> c f(x)g(x) = inifinity**

as required.

can someone please check this thanks
