# How do you graph #-3 cos x#?

graph{cos x [-10, 10, -5, 5]}

This should be the resulting graph:

graph{-3cos x [-10, 10, -5, 5]}

To graph $-3 \cos(x)$, you can start by understanding the graph of $\cos(x)$. The cosine function oscillates between -1 and 1. Multiplying it by -3 simply flips the graph vertically and stretches it vertically by a factor of 3. So, the amplitude becomes 3, and the graph is inverted. The horizontal axis (x-axis) remains the same. This means the maximum value is -3 and the minimum value is 3. The graph will follow the same pattern as the cosine function, but with inverted peaks and troughs.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
