To determine whether a given function is a function or a function onto the range added which may be made by considering the value of the slope of tangent curves. Therefore, the following theorem
Considering that the functions assigned to the function or functions on any range. May be based on the value of the slope of the tangent curve. The following theorem
Considering that the function that the increasing function or function on any range. Can the value of the slope of the tangent line curve as the following theorem.
