Question

Find the domain of single valued function y = (x) given by the equation 10x + 10y = 10.

Solution

Correct option is

x Ïµ (–∞, 1)

Given:

               10x + 10y = 1

⇒            10y = 10 – 10x    

Now,     101 – 10x > 0  

⇒         101 > 10x

⇒          1 > x

Hence, domain of single valued function 

              y = (x)  ⇒      x < 1
