Question
what is the domain of the function f(x)=1/root[2x-3]
Answers
Steve
the domain is all reals except where the denominator
a) is zero
b) is undefined
√(2x-3) = 0 when x = 3/2
√(2x-3) is undefined when 2x-3<0, or x<3/2
So, the domain is all x > 3/2
a) is zero
b) is undefined
√(2x-3) = 0 when x = 3/2
√(2x-3) is undefined when 2x-3<0, or x<3/2
So, the domain is all x > 3/2
