We have the next function

c=cost

t= number of tickets

[tex]c=25t[/tex]

and you have the constrain that you can buy up 5 tickets

Domain

[tex]\mleft\lbrace0,1,2,3,4,5\mright\rbrace[/tex]

Range

[tex]\mleft\lbrace0,25,50,75,100,125\mright\rbrace[/tex]

As we can see the domain is discrete because you can not buy for example half of the ticket we only buy integers.
