Write a rule for the linear function in the table.
x f(x)
1 3
2 2
3 1
4 0

A. f(x) = 4x

B. f(x) = x – 4

C. f(x) = x + 4

D. f(x) = 4 – x

• pre- algebra -

i put b i got it rong and it cant be c so its either a or d i think a

• pre- algebra -

D.

f( x ) = 4 - x

for x = 1

f ( x ) = 4 - 1 = 3

for x = 2

f ( x ) = 4 - 2 = 2

for x = 3

f ( x ) = 4 - 3 = 1

for x = 4

f ( x ) = 4 - 4 = 0
