Question

A relation P is defined as a set of ordered pairs $\left\{\right(-6,-2),(1,-1),(3,0),(5,1\left)\right\}$. What are the domain and Range of P ?

• A. Domain : $\{-6,1,3,5\}$
  Range : $-3<Z<2$
• B. Domain : $x\ge 0$
  Range : $\left(-2,-1,0,1\right\}$
• C. Domain : $x\ge 2$
  Range : $-2\le Z\le 1$
• D. All of the above.

Answer 1

The correct option is A Domain : $\{-6,1,3,5\}$

Range : $-3<Z<2$
Concept: Domain is set of first element of all ordered pairs of relation $P$.
Range is set of second element of all ordered pairs of relation $P$.

Domain:$\{-6,1,3,5\}$
Range $:\{-2,-1,0,1\}$ which can also be written as $-3<Z<2$
