Definition of Infinite Limit: Let XCR, f: X → R and a E X'. If for every M > 0
there exists > 0 such that f(x) > M whenever x € X and 0 < x-al < d then we
say that the limit as x approaches a of f(x) is ∞ which is denoted as lim f(x) = ∞.
x→a
Suppose a € R, € > 0, and f, g: N*(a, e) → R. If lim f(x) = L> 0 and lim g(x) = ∞,
prove lim (fg)(x) = ∞
