PLEASE HURRY 10 POINTS

A.
x 3 6 9 12
f(x) 6 12 18 24
B.
x 2 4 6 8
f(x) 5 9 13 17
C.
x 1 2 3 4
f(x) 1 3 13 17
D.
x 0 4 8 12
f(x) -1 7 15 23

Answer 1

D

Explanation:

x 0,4,8,12

f(x)‒1,7,15,23

we can prove as the following

f(x)=2x‒1

‒1=2(0)‒1

‒1=0‒1

‒1=‒1

f(x)=2x‒1

7=2(4)‒1

7=8‒1

7=7

f(x)=2x‒1

15=2(8)‒1

15=16‒1

15=15

f(x)=2x‒1

23=2(12)‒1

23=24‒1

23=23
