Step-by-step explanation:

Step 1: Define

Identify

g(x) = 2|x| - 1

Step 2: Evaluate

  1. Substitute in x [Function g(x)]:                                                                         g(-2.3) = 2|-2.3| - 1
  2. Absolute values:                                                                                               g(-2.3) = 2(2.3) - 1
  3. Multiply:                                                                                                             g(-2.3) = 4.6 - 1
  4. Subtract:                                                                                                            g(-2.3) = 3.6
3.6
2 *| -2.3 | - 1 = 3.6
