Math Problem Statement

Graph the function f(x) = -2x + 6 and complete the table of function values for x = -2, 0, and 2.

Solution

To complete the problem, follow these steps:

Step 1: Evaluate f(x)=2x+6f(x) = -2x + 6 for the given values of xx:

  1. For x=2x = -2: f(2)=2(2)+6=4+6=10f(-2) = -2(-2) + 6 = 4 + 6 = 10 So, f(2)=10f(-2) = 10.

  2. For x=0x = 0: f(0)=2(0)+6=0+6=6f(0) = -2(0) + 6 = 0 + 6 = 6 So, f(0)=6f(0) = 6.

  3. For x=2x = 2: f(2)=2(2)+6=4+6=2f(2) = -2(2) + 6 = -4 + 6 = 2 So, f(2)=2f(2) = 2.

Step 2: Complete the table:

xxf(x)f(x)
-210
06
22

Step 3: Plot these points on the graph:

  • Point 1: (2,10)(-2, 10)
  • Point 2: (0,6)(0, 6)
  • Point 3: (2,2)(2, 2)

Step 4: Draw the line:

The line passes through these three points and represents the function f(x)=2x+6f(x) = -2x + 6.
