Math Problem Statement

Complete the table and then graph the function y = 1/2x + 1 for x values -4, -2, 0, 6, and 8.

Solution

To solve this problem and complete the table for y=12x+1y = \frac{1}{2}x + 1, we will substitute the given xx-values into the equation and calculate yy.

  1. For x=4x = -4: y=12(4)+1=2+1=1y = \frac{1}{2}(-4) + 1 = -2 + 1 = -1

  2. For x=2x = -2: y=12(2)+1=1+1=0y = \frac{1}{2}(-2) + 1 = -1 + 1 = 0

  3. For x=0x = 0: y=12(0)+1=0+1=1y = \frac{1}{2}(0) + 1 = 0 + 1 = 1

  4. For x=6x = 6: y=12(6)+1=3+1=4y = \frac{1}{2}(6) + 1 = 3 + 1 = 4

  5. For x=8x = 8: y=12(8)+1=4+1=5y = \frac{1}{2}(8) + 1 = 4 + 1 = 5
