    Welcome to TeX.SE. Postings of the "do this for me-request" variety are generally discouraged on this site. Please tell us what you've tried so far. That does the "this" in "how to write this in LaTeX" refer to? The font style? All three lines shown in the screenshot, or just a subset of lines? Please be specific. – Mico Feb 05 '18 at 19:47

    See the cases environment of the amsmath package. – Steven B. Segletes Feb 05 '18 at 19:47

    Are $(a)$ and $(b)$ obtained by hand,or are they in an enumerate environment? – Bernard Feb 05 '18 at 20:07

\documentclass{article}

\usepackage{amsmath}
\usepackage{enumerate}

\begin{document}

\begin{enumerate}[(a)]
    \item
        \begin{align}
            y \equiv 0 &
        \end{align}
    \item
        \begin{align}
            \begin{cases}
                y = \left(\frac{2}{3}x\right)^{3/2} & x \ge 0 \\
                y = 0 & x \le 0
            \end{cases}
        \end{align}
\end{enumerate}

\end{document}

  • Thanks for taking care of this! Would you mind moving x to the numerator and replacing = by \equiv to make the thing a bit closer to the OP's picture? –  Feb 05 '18 at 21:56
