When expressing sets, you may write "inf" for infinity and "U" for union.

Write the complement of the given set in interval notation: (−[infinity],−5]

Answer:

(-5,[tex]\infty[/tex])

Step-by-step explanation:

We are given that a set in interval form

(-[tex]\infty[/tex],-5]

We have to find the complement of the given set.

Complement of set :If U={1,2,3,4} and A={1,2}

Then , complement of set A=U-A={3,4}

Therefore, here R=U

A=(-[tex]\infty[/tex],-5]

Complement of A=R-(-[tex]\infty[/tex],-5]=(-5,[tex]\infty[/tex])

Hence, the complement of given set=(-5,[tex]\infty[/tex])

Answer:

A. (-infinity,-9)U[-5,infinity)
