Not sure about the others but
b) 8,192
the pattern is multiplying by 8 each time for b
The zero property is anything multiplied zero to equal zero
Answers: A and D
-4.7x0=0
0x3=0
The answer is D. A function is to where a line can be drawn upon the y axis and not touch two points.
1) subtract 2y in both sides: (7y-2y)-6=(2y-2y)+8 which is 5y-6=8
2) Add 6 to both sides: 5y(-6+6)=8+6 which is 5y=14
3) Divide 5 on both sides: 5y/5=14/5 which is y=14/5 or y=2.8 or y=2 4/5
