11/14/2023 0 Comments Finding limits in calculus 3![]() Of Y is equal to g of x and once again pause this Just to get more cases of looking at graphical limits. The value of the function at x equals six, here theįunction was not defined at x equals four, but the limit does exist here the function is definedĪt f equals, x equals two but the limit does not existĪs we approach x equals two let's do another function In this first case theįunction is defined at six and the limit is equal to Would say that this limit does not exist so does not exist. Getting closer and closer to five and since we areĪpproaching two different values from the left hand sideĪnd the right hand side as x approached twoįrom the left hand side and the right hand side we It looks like our function the value of our function's To five but as we go from you know 2.1 2.01 2.001 Two from the right hand side, our function is gettingĬloser and closer to five it's not quite getting It looks like our function is approaching the value of two but when we approachįrom the right hand side, when we approach x equals See when we approach from the left hand side So this is interesting theįunction is defined there f of two is two, let's Least from what we can tell from the graph it looks like the limit of f of x is x approaches four is three, even though the function Limit exist at an x value where the function itself is not defined, the function, if you saidĪfter four, it's not defined but it looks like when weĪpproach it from the left when we approach xĮquals four from the left it looks like f is approaching three and then we approach four from the right, once again, it looks like ourįunction is approaching three so here I would say, at The value of our function it looks like it is approaching three. The limit of f of x is x approaches four so as we approach fourįrom the left hand side what is going on? Well as we approach fourįrom the left hand side it looks like our function, Like we are approaching one right over there, in a darker color. With a graph but this is a pretty good estimate, it looks ![]() Once again approaching one and in order for this limit to exist, we need to be approaching the same value from both the left and the right hand side and so here at least graphically, so you never are sure Six from the right hand side it looks like our f of x is X is approaching one and as we approach x equals In a color you can see, as x approaches six from both sides well as we approach sixįrom the left hand side, from values less than six, it looks like our f of Think about what's the limit of f of x it's x approaches six. If you can figure it out on your own before we do it together. Limit Properties.The graph of Y equals f of x right over here and we want to figure out three different limits and like always pause this video and see We begin by deriving a handful of theorems to give us the tools to compute many limits without explicitly working with the precise definition of a limit.
