Step-by-step explanation:

Step 1: Define

f(x) = 5x - 2

f(6) is x = 6

Step 2: Evaluate

  1. Substitute in x [Function]:                                                                                f(6) = 5(6) - 2
  2. Multiplication:                                                                                                    f(6) = 30 - 2
  3. Subtraction:                                                                                                       f(6) = 28

Answer:  28

=========================================================

Explanation:

Everywhere you see an x, replace it with 6

f(x) = 5x - 2

f(6) = 5*6 - 2

f(6) = 30 - 2

f(6) = 28

Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.
