You can see that the function is graphed for every number x that is greater than or equal to zero.
So we write that the domain is

.
Answer:
it is likely that a female will be picked
Step-by-step explanation:
the probability of selecting a female = 21/25....or 84%
43 < y - 30

y can be anything that is greater than 73
so it could be...
101, 74, 90, 75, 980767, 5674, etc.
Hope this helps!
Rationalize the numerator:

This is continuous at
, so we can evaluate the limit directly by substitution:
