" 1.A condition for a function "y=f(x)" to have an inverse is that it should be,"

Using examples,prove that the condition (dy)/(dx)=0 is neither a necessary nor a sufficient condition for a function y=f(x) to have a maximum or a minimumat a point.

A function f is have inverse it should be a bijection

A simple ciphertakes a number and codes it, using the function f(x)=3x-4. Find the inverse of this function, determine whether the inverse is also a function and verify the symmetrical property about the line y-x (by drawing the lines).

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= sqrt (2- sqrt x)

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= e^x - 3

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= e^ (2x-3)

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= root (3)( x-2)

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= log ( 2x-1)

Find the derivative of the function y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= 2x+3

Find the derivative of the fuction y=f(x) using the derivative of the inverse function x= f^(-1) (y) in the following: y= sqrt x
