For the first table, the y-values are not equally spaced and the ratios of y are not the same, but by plotting them and observing the graph that results, it looks like the points lie on an exponential curve. The second table is linear because when x changes by 1, y changes by 4. The third table is a quadratic model because even if the first differences of y are not the same, the second differences of y have the same value of 8. The fourth table is exponential because the ratio of y-values is 2, which is the same between each set of numbers.

Answer:In 8 years the tree will have the same height.
Step-by-step explanation:
Step 1:
Let x = the number of years when the two trees will be the same height.
For the 2ft tree, you can express its height in x years as:
2+1(x)
And for the 6ft. tree...
6+0.5(x)
Step 2:
2+x = 6+0.5x Subtract 0.5x from both sides.
2+0.5x = 6 Now subtract 2 from both sides.
0.5x = 4 Finally, divide both sides by 0.5
x = 8
Answer:
A straight line from 5,3 to1,6
The first one is the reverse of distributive property
it is normally written like a(b+c)=ab+ac
the 2nd is identity proprty of multilication
1 times anything is equal to the same number
usualy it is written as 1a=a
