Answer:
- b
- a
- c
Step-by-step explanation:
If the equation is in the form ...
y = ( )
then replace y with f(x).
If it is not in that form, solve for y so it is in that form.
__
The only equation that needs to have a solution is ...
y +4 = x
Subtracting 4 from both sides gives ...
y = x -4 ⇒ f(x) = x -4
The match is ...
- f(x) = -3x -4
- f(x) = x -4
- f(x) = x +4
