given f(x)=3x+4 and g(x)=x^2, evaulate each of the following:
#16. f(2a)
#17. g(4a)
#18. g(b^2)
#19. f(√b)
#20. f(x-2)
#21. g(x-4)
ok im srry if thats alot but i did the other 20 problems that were assigned to me for homework but i left this blank because i dont understand if anyone could just explain how to go about doing these 6 problems i would really appreciate it and dont give me the answer i need someone to really explain and break it down for me plz and thank you

F(x) = 3x+4 & g(x)= x^2
16. 3(2a) +4= 6a+4
17. (4a)^2 = 16a^2
18. (b^2)^2= b^4
19. 3 rad b + 4
20. 3(x-2) +4 = 3x -2
21. (x-4)^2 = x^2 -4x -4x+16 =
X^2-8x+ 16
16. 3(2a) +4= 6a+4
17. (4a)^2 = 16a^2
18. (b^2)^2= b^4
19. 3 rad b + 4
20. 3(x-2) +4 = 3x -2
21. (x-4)^2 = x^2 -4x -4x+16 =
X^2-8x+ 16
