Math Problem Statement

Complete the table by evaluating the function h(x)=−3x−1 for the given values of x.

x h(x)=−3x−1 −3 8 −2 −1 2 0 −1 1 2 3 −10

Solution

To complete the table for the function h(x)=3x1h(x) = -3x - 1, we need to evaluate the function for each given value of xx. Here's the step-by-step calculation:

  1. For x=3x = -3: h(3)=3(3)1=91=8h(-3) = -3(-3) - 1 = 9 - 1 = 8

  2. For x=8x = 8: h(8)=3(8)1=241=25h(8) = -3(8) - 1 = -24 - 1 = -25

  3. For x=2x = -2: h(2)=3(2)1=61=5h(-2) = -3(-2) - 1 = 6 - 1 = 5

  4. For x=1x = -1: h(1)=3(1)1=31=2h(-1) = -3(-1) - 1 = 3 - 1 = 2

  5. For x=2x = 2: h(2)=3(2)1=61=7h(2) = -3(2) - 1 = -6 - 1 = -7

  6. For x=0x = 0: h(0)=3(0)1=01=1h(0) = -3(0) - 1 = 0 - 1 = -1

  7. For x=1x = -1 (again): h(1)=2(calculated earlier)h(-1) = 2 \quad (\text{calculated earlier})

  8. For x=1x = 1: h(1)=3(1)1=31=4h(1) = -3(1) - 1 = -3 - 1 = -4

  9. For x=2x = 2 (again): h(2)=7(calculated earlier)h(2) = -7 \quad (\text{calculated earlier})

  10. For x=3x = 3: h(3)=3(3)1=91=10h(3) = -3(3) - 1 = -9 - 1 = -10

  11. For x=10x = -10: h(10)=3(10)1=301=29h(-10) = -3(-10) - 1 = 30 - 1 = 29

Here’s the completed table:

xh(x) = −3x − 1
-38
8-25
-25
-12
2-7
0-1
-12
1-4
2-7
3-10
-1029

Would you like any further clarification or examples? Here are some related questions:

  1. How would the graph of this function look?
  2. What is the slope and y-intercept of the equation h(x)=3x1h(x) = -3x - 1?
  3. How do we solve for xx when given h(x)=0h(x) = 0?
  4. What happens to the function when xx increases?
  5. How would the table look if the function were h(x)=2x+5h(x) = 2x + 5?

Tip: When evaluating a linear function like this one, just substitute the xx-values into the formula, and remember the general form y=mx+by = mx + b for slopes and intercepts!
