In this interactive figure, you can generate limit problems to solve. You can enter an [math]x[/math]-value or move the point on the curve to help with your exploration to help you figure out the solution. You want [math]x[/math] to get closer and closer to some specific value and hope to recognize what [math]f\left(x\right)[/math] is getting closer to.
