Even if a function is “normal”, like a linear function, we still consider the \(y\)-value a limit where it touches the \(x\)-value, as shown below. Now the beauty of limits is that \(x\) can get closer and closer to a number, but not actually ever get there (think asymptote from the Rational Functions section). We can write a limit where \(x\) gets closer and closer to 0 as \(\underset\)”. Again, remember that limits are always the \(y\)-value (dependent variable), not the \(x\)-value (independent variable). (Differential calculus has to do with rates at which quantities change.) I like to think of a limit as what the \(y\)-part of a graph or function approaches as \(x\) gets closer and closer to a number, either from the left-hand side (which means that \(x\)-part is increasing), or from the right-hand side (which means the \(x\)-part is decreasing).

We need to understand how limits work, since the first part of Differential Calculus uses them extensively. Also note that there’s a very good limit calculator here on the this online calculator site. Note that we discuss finding limits using L’Hopital’s Rule here.
