Answer 4

then you will get your answer ~

you know what's f(x) and f(1)?

Answer 5

no

Answer 6

f(x) = 3/(x+4) just as the question gives
to find f(1), substitute x = 1 into f(x)

Answer 7

ok

Answer 8

i will give you the answer in case ._., cos i gotta go

\[f(x) = \frac{3}{x+4}\]\[f(1) = \frac{3}5\]\[\huge \frac{\frac{3}{x+4}-\frac{3}{5}}{x-1}\]then solve algebraically you will get\[\frac{-3}{5x+20}\]

Answer 9

thank you
