Question

consider the function \\(f(x) = \sqrt{5x - 5} + 1\\)

which inequality is used to find the domain?

\\(5x - 4 \ge 0\\)

\\(\sqrt{5x - 5} + 1 \ge 0\\)

\\(5x \ge 0\\)

\\(5x - 5 \ge 0\\)

Explanation:

Identify the radicand of the square root function

$$ f(x) = \sqrt{5x - 5} + 1 $$

The radicand is \(5x - 5\).

Set up the domain inequality

$$ 5x - 5 \ge 0 $$

Answer:

  • (A) \(5x - 4 \ge 0\)
  • (B) \(\sqrt{5x - 5} + 1 \ge 0\)
  • (C) \(5x \ge 0\)
  • (D) \(5x - 5 \ge 0\) (Correct answer)
