Answer:
<em>Yes</em>
Step-by-step explanation:
g(x) = - x +
y = - x +
....... <em>(1)</em>
<em>(1)</em> × 4
4y = - x + 1
x = - 4y + 1
y = - 4x + 1
f(x) = - 4x + 1
∴ f(x) and g(x) <em>are inverses</em>
The best description of the car's motion as shown in the graph is: A. It travels for 1 hour, then stops for 1 hour, and finally travels again for 3 hours.
<h3>How to Analyze a Distance-Time Graph?</h3>In a distance-time graph, an horizontal line implies no distance was covered within that time frame, meaning there was a stop.
Thus, in the graph given, the stop occurred 1 and 2, which is equivalent to an hour. From 2 to 5 on the x-axis means there was movement for up to 3 hours.
Therefore, the best description is: A. It travels for 1 hour, then stops for 1 hour, and finally travels again for 3 hours.
