Answer 1

lets make a table

x 2^x
0 1
1 2
2 4
3 8
4 16
5 32

Answer 2

you see that every time you increase x by one unit, y doubles

Answer 3

x x^2
0 0
1 1
2 4
3 9
4 16
5 25

Answer 4

now every time x increases by 1 unit, y increases, but it does not double, it increases by consecutive odd numbers
1,3,5,7,9...

Answer 5

In order of growth:
2^x
x^2
2x
2^x will grow the fastest because as x gets larger and larger, you will be multiplying more and more but at an exponential rate. At some point, it will outdistance all the others. x^2 will grow the second fastest, because it is x multiplied by itself. 2x will grow the slowest because it simply adds two each time 1 is added to x.

Answer 6

finally
x 2x
0 0
1 2
2 4
3 6
4 8
5 10

now every time x increases by 1, y increases by 2 (the slope of the line is two) that is, you have a constant rate of increase
