Question 1079462
Typo? A mix-up of 2 problems?
The part that says
f''(x)= 2x +(1/root(3. x)
does not agree with the rest.
If {{{f(x)}}} is a function whose first derivative is the constant 2,
as in {{{"f ' (  x ) ="}}}{{{2}}} ,
then its second derivative is zero, {{{"f ' ' (  x ) ="}}}{{{0}}} ,
and {{{f(x)=2x+C}}} for some constant {{{C}}} .
If also {{{f(1)=2}}} then {{{2*1+C=3}}} , so {{{C=1}}} and {{{f(x)=2x+1}}} .
