HELP ME WITH THIS MATH QUESTION PLEASEE

Answer 1

Answer:

25. Option b.

26. Option d.

Step-by-step explanation:

25.

She earns $5.25 in one hour so in 1 hour 30 minutes = (1.5 hours) she earns 5.25  + 1.5*5.25 = 5.25 + 2.625

= $7.88.

26.  

The domain is {-8, -5 and 7} so it cannot be a or b.

 A function is either a one-to-one or a many-to-one relation

Look at option d . The  -8 in the domain maps on to 2 elements in the range

(-6 and 1) so its a one-to many relation and its NOT a function.
