limits equal to infinity By limits at infinity we mean one of the following two limits lim x f x lim x f x lim x f x lim x f x In other words we are going to be looking at what happens to a function if we let
mathop lim limits x to 0 frac 6 x 2 infty hspace 0 5in mathop lim limits x to 0 frac 6 x 2 infty hspace 0 5in mathop lim limits x to 0 frac 6 x 2 infty Find the limit of 2x x as x approaches infinity As I interpret the question as x approaches infinity the expression becomes 2 Since two times infinity is equal to infinity my answer will be which evaluates to 1

Definition Informal If the values of latex f x latex become arbitrarily close to latex L latex as latex x latex becomes sufficiently large we say the function latex f latex has a limit at infinity and write A function displaystyle f x frac 1 x n for any value of n gt 0 has the following limits to infinity and negative infinity begin equation lim x to infty frac 1 x n 0 lim x to infty
As x approaches infinity 1 x approaches 0 We would write this mathematically as lim x to infty frac 1 x 0 We can also see this graphically using Mathway Notice in the graph below that as the x So for graph A the limit as x approaches one from the left that looks like it s unbounded in the positive direction That equals infinity and the limit as X approaches one from the
