I am very new to such online forums so please forgive me for any mistake i might have made.
f(x)=5
This is a real valued function and defined on all points.
what is the Derivative of f(x) at x=0?
so the way i solved is below...
f'(x)= f (x+h)-f(x)/h when lim h tends to 0
because x=0
It gives us f'(x)= 5-5/0 = 0/0 which is undefined
i don't know where did i go wrong. as
I myself intuitively feel that it should be 0 as this function's slope is 0 everywhere.
Can someone please help how come it has 2 answers?
Thank you for you help in advance.
