#### Answer

Refer to the image below for the graph.
The graph of $f(x)$ is orange, the graph of the parent function is blue.

#### Work Step by Step

RECALL:
The graph of the function $f(x) = -a^x$ involves a reflection about the x=axis of the parent function $y = a^x$.
The given function $f(x) = -3^x$ has its parent function $y = 3^x$.
The graph of the given function is a reflection about the x-axis of the parent function.
Thus, to graph the given function, perform the following steps:
(1) Graph the parent function $y = 3^x$ by creating a table of values then connecting the points using a smooth curve.
(refer to the attached table below, the graph is attached in the answer part above)
(2) Draw the graph of $f(x)$by reflecting the points of the parent function about the x-axis. This can be achieved by plotting the negative (or opposite sign) of each y-value of the parent function (e.g., if (0, 1) is in the parent function, (0, -1) is in f(x)).
The graph of $f(x)$ is orange, the graph of the parent function is blue.
