Question: Which of the following is the correct representation of the modulus function?
Options:
(A) $f(x) = |x|$
(B) $f(x) = x^2$
(C) $f(x) = \sqrt{x}$
(D) $f(x) = \frac{1}{x}$
Show Answer
Answer: A
Explanation:
(A) Correct. The modulus function is represented as $f(x) = |x|$, which gives the absolute value of x.
(B) Incorrect. This represents a quadratic function, not the modulus function.
(C) Incorrect. This represents the square root function, not the modulus function.
(D) Incorrect. This represents the reciprocal function, not the modulus function.
