If f x 2x 2 what is f f 3 a 18 b 8 c 64 d 16

f(3)=2*3+2=8
now put this value again in the function
f(8)=2*8+2=18
10 years agoHelpfull: Yes(4) No(0)
f(x)=2x+2
f(f(x))=2(2x+2)+2
now put x=3
f(f(3))=2(2*3+2)+2)=18
ans c

18

because f(3) is 8 and f(8) is 18.

f(x)=2X+2;
f(f(3))=?;
f(3)=2(3)+2=8;
f(8)=2(8)+2=18;
ans:18

18
f((3)=8
f(f(3)=f(8)=18
10 years agoHelpfull: Yes(0) No(0)
18 is the answer
10 years agoHelpfull: Yes(0) No(0)
18
f(3)=2*3+2=8
f(8)=2*8+2=18
9 years agoHelpfull: Yes(0) No(0)
f(f(x))=2(2x+2)+2
so,f(f(3))=2(6+2)+2
=18
9 years agoHelpfull: Yes(0) No(0)
f(x) = 2x+2
f(3) = 2*3+2=8

f(f(3))= 2*f(3)+2 = 2*8+2 = 18
9 years agoHelpfull: Yes(0) No(0)
f(3)=2*3+2=8
f(f(3))=f(8)=2*8+2=18
so............. ANS:18
9 years agoHelpfull: Yes(0) No(0)
f(x)=2x+3
f(f(3))=2(2*3+2)+3
=18
9 years agoHelpfull: Yes(0) No(0)
f(3)= 2*3+2= 8 and correspondingly f(8)= 2*8+2=18
8 years agoHelpfull: Yes(0) No(0)
option is a 18
7 years agoHelpfull: Yes(0) No(0)
a.18
first solve f(3)=8 and sustitue value ox x on eqn =18
7 years agoHelpfull: Yes(0) No(0)
18
f(f(3)=f(2(3)+2);
f(8)=2*8+2;
18;
7 years agoHelpfull: Yes(0) No(0)
18 because f(3)is 6 and f(f(3)is 18 we substitute in x
7 years agoHelpfull: Yes(0) No(0)
18.
f(3)=6+2=8
now put it into f(x)
so...f(8)=16+2=18
7 years agoHelpfull: Yes(0) No(0)
Here, given f(x)=2X+2 and now
f(3)= 2(3)+2=8
therefore, f(3)=8
now f(8)=2(8)+2=18

If f(x) = 2x+2 what is f(f(3))?
a. 18
b. 8
c. 64
d. 16
