Respuesta :

Given C and D are sets of real numbers:

[tex]\begin{gathered} C=\mleft\lbrace y\mright|y\ge1\} \\ D=\mleft\lbrace y\mright|y<8\} \end{gathered}[/tex]

So, the intervals of C and D will be as follows:

[tex]\begin{gathered} C\colon\lbrack1,\infty) \\ D\colon(-\infty,8) \end{gathered}[/tex]

We will find the following:

[tex]\begin{gathered} C\cap D=\lbrack1,8) \\ C\cup D=(-\infty,\infty) \end{gathered}[/tex]
