What is the <strong>MINIMUM</strong> value of the function f(x)=\log_{10}(x^{2}+2x+11)?

  1. A. 0
  2. B. 1
  3. C. 2
  4. D. 10

Correct Answer: B. 1

Explanation

Complete the square for the quadratic expression: x^2 + 2x + 11 = (x+1)^2 + 10. The minimum value of (x+1)^2 is 0, which occurs at x = -1. Therefore, the minimum value of the expression inside the logarithm is 10. The minimum value of the function is f(-1) = \log_{10}(10) = 1.
