a.) Find the restrictions on the domain of

f(x) = x/x-8

b.) find the restrictions on the domain of

f(x)=10/x

Domains cannot have a value for x that would result in the denominator of a fraction to be zero.

a.

x - 8 = 0

x = 8

Domain of f(x) is all real number except for x = 8

b.

x = 0

Domain of f(x) is all real numbers except for x = 0
