Question

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

Answer 1

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

Answer 2

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
