Answer 1

I apologize, but I'm unable to view or access external websites. However, I can help you understand how to graph the given function and find its values for specific arguments.

Graphing the Function:

To graph the function, we need to plot points on a coordinate plane based on the given function values for different values of x.

The given function is defined as follows: - For x ≤ -2, y = 2 - For 2 ≤ x < 2, y = -2x - 1 - For x ≥ 2, y = 2x - 3

Let's plot the points for different intervals of x:

For x ≤ -2: - When x = -3, y = 2 - When x = -2, y = 2

For 2 ≤ x < 2: - When x = 2, y = -2(2) - 1 = -5 - When x = 1, y = -2(1) - 1 = -3 - When x = 0, y = -2(0) - 1 = -1

For x ≥ 2: - When x = 2, y = 2(2) - 3 = 1 - When x = 3, y = 2(3) - 3 = 3

Now, let's plot these points on a graph:

     |
  3  |       o
     |
  2  | o
     |
  1  |       o
     |
  0  | o
     |
 -1  |       o
     |
 -2  | o     o
     |
 -3  |       o
     |
     ---------------
      -3 -2 -1  0  1  2  3

Finding the Values of the Function:

Now, let's find the values of the function for the given arguments: 0, -7, -2, 4, and -2.6.

For x = 0: - Since 0 is between -2 and 2, we use the second equation: y = -2x - 1 - Substituting x = 0, we get y = -2(0) - 1 = -1

For x = -7: - Since -7 is less than -2, we use the first equation: y = 2 - Therefore, y = 2

For x = -2: - Since -2 is between -2 and 2, we use the second equation: y = -2x - 1 - Substituting x = -2, we get y = -2(-2) - 1 = 3

For x = 4: - Since 4 is greater than 2, we use the third equation: y = 2x - 3 - Substituting x = 4, we get y = 2(4) - 3 = 5

For x = -2.6: - Since -2.6 is between -2 and 2, we use the second equation: y = -2x - 1 - Substituting x = -2.6, we get y = -2(-2.6) - 1 = 4.2

Therefore, the values of the function for the given arguments are: - For x = 0, y = -1 - For x = -7, y = 2 - For x = -2, y = 3 - For x = 4, y = 5 - For x = -2.6, y = 4.2

I hope this helps! Let me know if you have any further questions.
