  • How do you prove that a function is continuous everywhere?

    For a function to be continuous at a point, it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point. Discontinuities may be classified as removable, jump, or infinite.
  • How do you verify a continuous function?

    A real function f is continuous if it is continuous at every point in the domain of f. We can explain this in detail with mathematical terms as: Suppose f is a function defined on a closed interval [a, b], then for f to be continuous, it needs to be continuous at every point in [a, b], including the endpoints a and b.
  • All polynomial functions are continuous functions. The trigonometric functions sin(x) and cos(x) are continuous and oscillate between the values -1 and 1.
