Look at the picture.

Answer:
a. f(x) = log x + 3

[tex]f(x)=\log x\xrightarrow{T_{ \ \textless \ 0;\ 3 \ \textgreater \ }} f(x)=\log x+3\\\\/3\ usnits\ up/[/tex]

Answer: a. f(x)=logx+3

Step-by-step explanation:

here, value of the function at 1 is 3 i.e. f(1)=3

since, log1=0

a)

f(x)= logx+3 satisfies f(1)=3

b)

f(x)=log(x+3)

f(1)=log4

    = 1.3863≠3

c)

f(x)=logx-3

f(1)=-3≠3

d)

f(x)=logx-1

f(1)=-1≠3

hence, option a. f(x)=logx+3 is correct
