help :(

Question

complete the table of the values for each exponential function. decimal cannot be rounded. yoou must fractions in a case where the decimal is repeating or non terminating.

y=4*
x	y
-3
-2
-1
0
1
2
3

 

 

y=2(1/2)*
x	y
-3
-2
-1
0
1
2
3

 

y=2(3)*
x	y
-3
-2
-1
0
1
2
3

 

Answer 1

1)

y = 4x
x	y
-3	4-3 = 1/43 = 0.015625
-2	4-2 = 1/42 = 0.0625
-1	4-1 = 1/4 = 0.25
0	40 = 1
1	41 = 4
2	42 = 16
3	43 = 64

 

Answer 2

2)

y = 2(1/2)x
x	y
-3	2(1/2)-3 = 2(8) = 16
-2	2(1/2)-2 = 2(4) = 8
-1	2(1/2)-1 = 2(2) = 4
0	2(1/2)0 = 2(1)  = 2
1	2(1/2)1 = 2(1/2) = 1
2	2(1/2)2 = 2(1/4) = 0.5
3	2(1/2)3 = 2(1/8) = 0.25

Comments

Sorry it was suppose to be y=4(1/2)* thanks

---

2)

y = 4(1/2)x
x	y
-3	4(1/2)-3 = 4(8) = 32
-2	4(1/2)-2 = 4(4) = 16
-1	4(1/2)-1 = 4(2) = 8
0	4(1/2)0 = 4(1)  = 4
1	4(1/2)1 = 4(1/2) = 2
2	4(1/2)2 = 4(1/4) = 1
3	4(1/2)3 = 4(1/8) = 0.5

 

Answer 3

3)

y = 2(3)x
x	y
-3	2(3)-3 = 2(1/27) = 2/27
-2	2(3)-2 = 2(1/9) = 2/9
-1	2(3) -1 = 2(1/3) = 2/3
0	2(3)0 = 2(1) = 2
1	2(3)1 = 2(3) = 6
2	2(3)2 = 2(9) = 18
3	2(3)3 = 2(27) = 54
