Question

if x/2 =4.., then the value of 2x+6 is equal to​

Answer 1

Answer:

Answer

Correct option is

C

f(12)

Given f(x)=2x+4

f(4)=2×4+4=12

f(6)=2×6+4=16

f(4)+f(6)=12+16=28

Substituting the values of 8,10,12,18,28 as x in f(x), we get

f(8)=2×8+4=20

f(10)=2×10+4=24

f(12)=2×12+4=28

f(18)=2×18+4=36

f(28)=2×28+4=60

Hence correct value is C.f(12)=2×12+4=28
