Answer:
Option d is correct.
Step-by-step explanation:
Discrete values are those which take an integer value not in fraction.
Option A is discrete because there will be certain number of students in class say 20 or 30
We can not have 20.5 students
Therefore, option a is correct.
Option B is not discrete because many people can have age say 65 and a half years and weight can be in decimals say 50.5 kgs.
Option C is correct because he is saving a proper integer number of money.
Therefore, option d is correct that is both A and C are correct.

Answer: 74</h3>
==================================================
Work Shown:
h(x) = 7x-5
h(2) = 7(2)-5
h(2) = 14-5
h(2) = 9
f(h(2)) = f(9)
f(x) = x^2-7
f(9) = 9^2-7
f(9) = 81-7
f(9) = 74
f(h(2)) = 74
-----------
Here's a slightly alternative approach:
f(x) = x^2 - 7
f(h(x)) = ( h(x) )^2 - 7
f(h(x)) = ( 7x-5 )^2 - 7
f(h(2)) = ( 7*2-5 )^2 - 7
f(h(2)) = ( 14-5 )^2 - 7
f(h(2)) = ( 9 )^2 - 7
f(h(2)) = 81 - 7
f(h(2)) = 74
5 + (8*y) = h
This was the best I could think of, please let me know if I'm wrong.
