- Definition of infinite limit: Let X⊆ R, f: X -> R and a∈ X'. If for every M>0 there exists delta > 0 such that |f(x)| > M whenever x∈X and 0< |x-a| < delta then we say that the limit as x approaches a of f(x) is ∞ which is denoted as lim {x-> a} f(x) = ∞. Suppose a∈R, ∈>0, and f,g : N*(a,∈) ->R. If lim {x-> a} f(x) = L>0 and lim {x-> a} g(x)= ∞, prove lim {x-> a} (fg)(x)=∞.arrow_forwardlim n->infinity (Un) = L how do i prove that this is only the case if lim n-> infinity ('U^2' n) = L^2. Using the definiton for a limit ie using epsilonarrow_forwardtrue or false questions. please explain why. . 1-if lim_{x->a} f(x)=∞ and y=g(x) is defined and bounded below on an interval containing a , then lim_{x->a} f(x)+g(x)=∞ 2- if 0≤a≤1/e , then the equation x.e^-x=a has a nonnegative solution. 3-suppose that a function y=f(x) is continuous on I=[a,b] and if the set f(I)=[f(a),f(b)], then y=f(x) is strictly increasing.arrow_forward
