Math Problem Statement

Complete the table of values based on the expression Y = -1x - 2 for the given inputs.

Solution

In the image, you are working with an "Input and Output Table" where the expression for the output (Y) is given as Y=1x2Y = -1x - 2. Let's calculate the output (Y) values for the corresponding inputs (X).

The rule is:
Y=1x2Y = -1x - 2

  1. For X=1X = -1: Y=1(1)2=12=1Y = -1(-1) - 2 = 1 - 2 = -1 So, Y=1Y = -1.

  2. For X=0X = 0: Y=1(0)2=02=2Y = -1(0) - 2 = 0 - 2 = -2 So, Y=2Y = -2.

  3. For X=1X = 1: Y=1(1)2=12=3Y = -1(1) - 2 = -1 - 2 = -3 So, Y=3Y = -3.

  4. For X=3X = 3: Y=1(3)2=32=5Y = -1(3) - 2 = -3 - 2 = -5 So, Y=5Y = -5.

Now, the complete table should look like this:

Input (X)Output (Y)
-1-1
0-2
1-3
3-5

Let me know if you need more details or have further questions!

Here are 5 related questions you might find useful:

  1. How would the outputs change if the rule was Y=2x2Y = -2x - 2?
  2. What happens to the output when the input XX is a larger positive number, like 5 or 10?
  3. Can you describe the relationship between the input and output in this linear function?
  4. How could you graph the points (1,1),(0,2),(1,3),(3,5)(-1, -1), (0, -2), (1, -3), (3, -5)?
  5. What happens if you use a positive coefficient in the rule instead of -1?

Tip: Linear equations of the form Y=mx+bY = mx + b describe straight lines, where mm is the slope and bb is the y-intercept.
