Question
Here’s how I solved it but u don’t know how to write the final solution and match it to the option could you please explain the half line and disjoint open bounded intervals and give me some brief example
1) Domain f(x) = ln (2x²-26) and bounded interval open b) union of disjoint intervals c) union of two disjoint half-lines I think it's B⇒ 2x²-x²>0 ⇒ 24 (2-x²) >0 ⇒ x (NZ 20

Follow-up Question

okay but according to your answer if i substitute 0 since its included in the interval i should get a defined function, but with 0 the function becomes undefined so check your work again please
