Answer:
Absolute Value function.
Step-by-step explanation:
- Absolute Value refers to the distance of a number from 0, the distances are positive regardless of the direction of distance.
- Absolute value of a number cannot be negative as distance is always positive.
- Absolute value function can be defined as
\(f(x) = \mid x \mid = x, x > 0\\~~~~~~~~~~~~~~= -x, x < 0\)
1)
\(f(-1) = \mid -1 \mid = -(-1) = 1\)
2)
\(f(\frac{1}{3}) = \mid \frac{1}{3} \mid = \frac{1}{3}\)
