Function Evaluation and Results

Function Evaluation

• Function: $f(x) = x + 6x + 1$
• Simplification:
  • Combine like terms: $f(x) = 7x + 1$

Evaluation at Specific Values

• a. Evaluating at 6:

  • $f(6) = 7(6) + 1 = 42 + 1 = 43$

• b. Evaluating at (x + 9):

  • $f(x + 9) = 7(x + 9) + 1 = 7x + 63 + 1 = 7x + 64$

• c. Evaluating at x:

  • $f(x) = 7x + 1$
