Questions: Sketch the graph of the given function. y=-3 cos x

Transcript text: Sketch the graph of the given function. \[ y=-3 \cos x \]

Solution

Solution Steps

Step 1: Identify the Function

The given function is: \[ y = -3 \cos x \]

Step 2: Determine the Range for Plotting

To sketch the graph of $ y = -3 \cos x $, we need to determine a suitable range for $ x $. A typical range for cosine functions is from $ -2\pi $ to $ 2\pi $.

Final Answer

The function to be plotted is $ y = -3 \cos x $ over the range $ x \in [-2\pi, 2\pi] $.
