What function is graphed below?

a. f(x) = log x + 3
b. f(x) = log (x + 3)
c. f(x) = log x – 3
d. f(x) = log x – 1

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
