(Calculus/Limits ) Find Epsilon-Delta Limit of x Squared [ University Calculus 1 ] [Limits]

This Video (based on our math blog and class recordings)outlines a step-by-step process for determining a specific value, delta, within the context of an epsilon-delta limit definition. It focuses on the function y equals x squared as x approaches two, aiming to ensure the output y is within a given tolerance of four. The explanation details how to algebraically manipulate the difference between y and four, specifically by factoring the expression. Furthermore, it demonstrates how to constrain the possible values of x to establish an upper bound for one part of the factored expression. Finally, the text illustrates how to calculate the required delta value to guarantee the desired proximity of y to four.
