Question

Find Domain of the function

square root of (x-8)/x(x-9)

Answer 1

Yo sup??

Domain refers to the permissible values of x

since the given function won't be defined at x=0 and x=9

Also the value of the given function should be greater than 0 or else the square root function won't be defined

therefore the domain of the function is :

R+-{0,9}

Hope this helps.

Answer 2

Domain of your function is D = (0,8]U(9, +oo).
