Explanation:
From the following figure, We can see that we have a graph with different lines where some points are included and some are not . Let's find out the listed values using graph:
F(-10):
From the graph F(-10) = -6 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
F(-4):
From the graph F(-4) = 0 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
F(-2):
From the graph F(-2) = 2 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
F(0):
From the graph F(0) = -1 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
F(3):
From the graph F(3) = -7 , basically we draw a horizontal line from value of x in graph and see where does that line cut y-axis , and that point is the value of function .
