Graph the function defined by f(x)= |-x-7|

 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.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
