Question

Write a rule for the linear function in the table.
x f(x)
–3 –1
0 2
3 5
6 8

A. f(x) = x + 2

B. f(x) = 3x

C. f(x) = x – 2

D. f(x) = x – 1

Answer 1

what you can do is for each choice, plug in each x,y pair and see which equation is satisfied for all 4 pairs

Answer 2

for instance, let's check choice B

Answer 3

f(x) = 3x

2 = 3*0 ... plug in x = 0 and f(x) = 2

2 = 0

this equation is false, so choice B is out

Answer 4

Choice A.

Answer 5
