Domain of Logarithmic Equation

Find Domain of Log Equation.

y = logsub10 (2x + 3/x - 5)

-
x can not equal 5: because that would make the denominator within the log function zero and the fraction would be undefined.

x can not equal -3/2 because log is undefined at zero

so the domain can be written in interval form as (0,-3/2)U(-3/2,5)U(5,infinity)
