The ordered pair (-3 , ) is on g(x) ⇒ 1st answer
Step-by-step explanation:
Let us revise the reflection across the axes
- If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x) (change the sign of y)
- If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x) (change the sign of x)
∵
∵ f(x) is reflected across the y-axis to create the function g(x)
- Change the sign of x
∴
To find the point that lies on g(x) substitute x in g(x) by the x-coordinate of the point if the answer equal to the y-coordinate of the point, then the point lies on it if not then the point does not lie on it
∵ The coordinates of the point are (-3 , )
∴ x = -3 and y =
- Substitute x by -3 in g(x)
∵
∴
∴
∵
∴
∴
- Divide up and down by 2
∴
∵ The value of g(x) equal to the y-coordinate of the point
∴ The point (-3 , ) lies on g(x)
The ordered pair (-3 , ) is on g(x)

The graph is missing, so I am using a graph for a similar question.
It migh even be the same question, but the important thing is that I am going to explain you the situation in several sections of this diagram and so you will be able to work this kind of problems by your selfl.
The graph is attached (see the figure).
The graph shows the evolution of the speed (vertical-axis) over time (horizontal-axis).
In the section A, the speed increases linearly: so the car is speeding up uniformly (constant acceleration).
In the section B, the line is horizontal which shows that the speed is constant. That is a uniform motion.
In the section C, the speed is decreasing uniformly, so the car is slowing down with uniform negative acceleration.
So, for this graph, the answer is: in the setion C. the car is slowing down (uniformly).
