How do you determine the absolute maximum and minimum values of the function f(x) = 2 – x² over the interval [-1, 1] and where these extrema are located?

To find the absolute maximum and minimum values of the function f(x) = 2 – x² over the interval [-1, 1], we can follow a systematic approach that includes checking the endpoints of the interval as well as any critical points within the interval. Step 1: Identify the Critical Points A critical point occurs where … Read more

What does it mean for a function to be discontinuous at a specific point, and why does that happen at point ‘a’?

Understanding Discontinuity in Functions Discontinuity in a function arises when the function fails to meet certain criteria at a specific point. For a function to be continuous at a point ‘a’, it must satisfy three main conditions: The function is defined at ‘a’. The limit of the function as it approaches ‘a’ must exist. The … Read more
