Question 1088767: If f(x)=x+7 and f(g(2))=3, which if the following functions could be g(x)?
A. X-6
B. X+6
C. 3x-1
D. 2x-1
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
If the first is substituted, the function is x-6+7=x+1, and f(2)=3.
If the second is substituted, the function is x+13, doesn't work
the third becomes 3x+6, which doesn't work
The fourth becomes 2x+6 which also doesn't work.
A.
