The domain of the following relation: r: {(-3, 4), (5,0), (1, 5), (2, 8), (5, 10)} is (1 point)
{-3, 1, 2, 5)
{4, 0, 5, 8, 10)
{-3, 5, 1, 2,5}
no domain exists

{-3,1,2,5}

Step-by-step explanation:

The domain is the input values

(-3,1,5,2,5)

We only list the 5 one time

{-3,1,2,5}

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
