How to create 3 subfloat (a) (b) (c) for 1 figure?

Question

I have a script that generates a figure

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{float}
\usepackage{subfig}
\usepackage{graphicx}
\begin{document}

\begin{figure}
\subfloat[]{\includegraphics[width=1\textwidth]{example-image-a}}
\caption{}
\end{figure}

\end{document}

However, I would like to have

(a) text <manual spacing> (b) text <manual spacing> (c) text

How can I achieve this? For example, something like \subfloat[][][]{\includegraphics[width=1\textwidth]{example-image-a}}

Answer 1

\begin{figure}
     \centering
     \begin{subfigure}[b]{0.3\textwidth}
         \centering
         \includegraphics[width=\textwidth]{graph1}
         \caption{$y=x$}
         \label{fig:y equals x}
     \end{subfigure}
     \hfill
     \begin{subfigure}[b]{0.3\textwidth}
         \centering
         \includegraphics[width=\textwidth]{graph2}
         \caption{$y=3sinx$}
         \label{fig:three sin x}
     \end{subfigure}
     \hfill
     \begin{subfigure}[b]{0.3\textwidth}
         \centering
         \includegraphics[width=\textwidth]{graph3}
         \caption{$y=5/x$}
         \label{fig:five over x}
     \end{subfigure}
        \caption{Three simple graphs}
        \label{fig:three graphs}
\end{figure}

Answer 2

I solved it by adding (a) text <manual spacing> (b) text <manual spacing> (c) text into the figure itself so now I can have 1 figure with 3 captions.
