# Vertically Align Multiple Horizontal Lists

I'm trying to achieve the following: So I'd like to have in-line lists, that our flush with the left margin and vertically aligned with each letter. I achieved the result above by manually spacing, which is not ideal. I can't seem to find an environment that covers each of the above conditions.

Using the following answers: How to make horizontal lists? I can achieve the following:

\usepackage{tasks}
\begin{tasks}[counter-format={(tsk[a])}, label-align=left, label-offset={0mm}, label-width={5mm}, item-indent={5mm}, label-format={\bfseries}, column-sep=-30mm, after-item-skip=-1mm, after-skip={3mm}](2)
\task $f(5)$
\task $f(x+h)$
\task $f(x+h) - f(x)$
\task $\dfrac{f(x+h)-f(x)}{h} \quad h\neq 0$ \end{tasks}


I don't know how to put a space between the letter and the expression. For example: (a)[INSERT SPACE HERE] f(5). Adjusting the parameters listed in the code above seems to adjust other things. Using ":/" in math mode works, but it's not an ideal solution.

You need to adjust the label-width and item-indent settings to be larger:

\documentclass{article}

\usepackage{amsmath,tasks}

\begin{document}

\begin{tasks}[
label={(\alph*)},
label-align=left,
label-offset={0mm},
label-width=20pt,
item-indent=20pt,
label-format={\bfseries},
column-sep=-30mm,
after-item-skip=-1mm,
after-skip={3mm}](2)
\task $f(5)$
\task $f(x + h)$
\task $f(x + h) - f(x)$
\task $\dfrac{f(x + h) - f(x)}{h} \quad h \neq 0$
\end{tasks}

\end{document}
