hartnn (hartnn):

know the formula?

hartnn (hartnn):

\(\Large \dfrac{f(b)-f(a)}{b-a}\)

Directrix (directrix):

Is the function supposed to be f(x)=sqrt(4x+1) rather than f(x) = sqrt(4x) + 1 ?

Directrix (directrix):

Check this and see if you think it conforms to hartnn's statement of the formula. |dw:1449561489571:dw|
