A test car travels in a straight line along the x -axis. The graph in the figure shows the car’s position as a function of time. At which point is the velocity zero? will give brainliest

The graph is of position. Velocity is the rate of change of position, the slope of the graphed curve. The slope is zero where the graph is horizontal, at points C and G.
Answer:
C and G
Step-by-step explanation:
The velocity is the first derivative of the function position X(t), or, the rate of the change [tex]\dfrac{dX}{dt}[/tex] of the position X with respect of the time t. In the graph, to see at which point the velocity is equal to zero, we have to see when the slope of the tangent line at a given point is equal to zero, or in other words, when the tangent line at a given point is horizontal and this is exactly the case for the points C and G.
