14. f(10)
16. f(a)
18. g(10)
20. g(a)
22. h(10)
24. h(a)
15. f(-2)
17. f(a+b)
19. g(-2)
21. g(a + b)
23. h(-2)
25. h(a+b)

Answer 1

Explanation:

f(x) = x

g(x) = 5x - 12

h(x) = x² + 4x - 7

===============

14. f(10) = 10

16. f(a) = a

18. g(10) = 38

20. g(a) = 5a - 12

22. h(10) = 133

24. h(a) = a^2 + 4a - 7

15. f(-2) = -2

17. f(a+b) = a + b

19. g(-2) = -12
