Graph the function defined by f(x)= |-x-7|
1 answer:
Answer: The answer is the third graph, attached herewith the image.
Step-by-step explanation: The given function is
We are to select the correct graph from the given four options that is defined by the function above.
At x = 0, y = 7
and
at y = -7, y = 0.
So, the points (0, 7) and (-7, 0) satisfies the given function and hence these points must lie on the graph also.
We can see that the points (0, 7) and (-7, 0) lie only on the third graph. The image is attached with these two points plotted.
Thus, the answer is the third graph.

Answer:
If the line is parallel to the x-axis than only x value changes and y value remains constant.
Step-by-step explanation:
Consider the provided information.
We need to draw three lines that are parallel to the x-axis.
The required graph is shown below:
Now the ordered pairs for points on each line is:
For line y=-3 The ordered pairs are (-1,-3), (0,-3) and (1,-3)
For line y=2 The ordered pairs are (-2,2), (2,2) and (3,2)
For line y=4 The ordered pairs are (-3,4), (0,4) and (4,4)
Here we can observe the x value changes but y values remains constant.
Therefore, if the line is parallel to the x-axis than only x value changes and y value remains constant.
