A real valued function is at a point in its domain if the limit of the function at that point equals the value of the function at that point.

A function is continuous if it is continuous on the whole of its .

Sum, difference, product and quotient of continuous are continuous.

Every differentiable function is continuous, but the is not true.

differentiation is a powerful technique to differentiate functions of the form f(x) = [u (x)]v (x).

Theorem: If f : [a, b] → R is continuous on [a, b] and differentiable on (a, b) such that f(a) = f(b), then there exists some c in (a, b) such that f ′(c) = 0.

Theorem: If f : [a, b] → R is continuous on [a, b] and differentiable on (a, b).

A function is at x = c if the function is defined at x = c and if the value of the function at x = c equals the limit of the function at x = c.

Suppose f and g be two continuous at a real number c.Then f + g is continuous at x = c

(uv)′ = u′v + uv′ is rule.

Function is a function in which the dependent variable can be written explicitly in terms of the independent variable.

Function is a function or relation in which the dependent variable is not isolated on one side of the equation.

of the exponential function is R, the set of all real numbers.

of the exponential function is the set of all positive real numbers.

Exponential function with base 10 is called the function.

Exponential function y = eⁿ.This is called function.

The range of log function is the set of all numbers.
