So I use the formula hopefully these steps work
The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
Simplifies to y=2x-12. slope intercept form is y=MX+b where m is slope and b is intercept do slope 4 and y intercept is -12
Answer:

Step-by-step explanation:

The answer choice that is false is D.
The form of the y-intercept is (0,Y). Remember that x comes first in an ordered pair and y comes second.
Hope this helps!
