Question 1191136
<font face="Times New Roman" size="+2">


I presume you mean *[tex \Large f(x)\ =\ \sqrt[3]{x\,-\,\frac{2}{5}}] although there is no reason not to interpret your input as *[tex \Large f(x)\ =\ \sqrt[3]{x}\ -\ \frac{2}{5}] or *[tex \Large f(x)\ =\ \frac{\sqrt[3]{x\,-\,2}}{5}]. Use parentheses to make clear what elements of your text are inside radicals and what goes in fraction numerators and denominators when you re-post.  Also, the plain text representation of cube root is "cbrt()" or "sqrt[3]()".  By the way, one question per post.  You posted four questions.
