1. The problem statement, all variables and given/known data For the Constant function f(x)=c prove that f'(x)= 0 2. Relevant equations Alright so the relevant equation would be the Difference quotient or definition of a derivative. 3. The attempt at a solution This is what I said I restated the equation as this f(x)=c >>>> f(c)= c(x^0) Then I imputed into definition of derivative (c(x+h)^0 - c(x^0))/ h Then I solved it to be (c-c)/h = 0/h and then set h to 0 and then you get 0/0 which is non determinant form. I am not sure if this "proves" the statements to be true or if since it is 0/0 that doesn't show anything.
