Step 1: Define

Identify

[Function] f(x) = 6x + 1.5

[Given] f(2.5) is x = 2.5 for function f(x)

Step 2: Evaluate

  1. Substitute in x [Function f(x)]:                                                                           f(2.5) = 6(2.5) + 1.5
  2. Multiply:                                                                                                             f(2.5) = 15 + 1.5
  3. Add:                                                                                                                   f(2.5) = 16.5
