Answer:

A: Exponential

B: Quadratic

C: Linear

Step-by-step explanation:

Solution:-

- We will closely inspect each Table and find the difference between each "Y" value at every unit increase in "x" value:

Table A:

 X            Y              ΔY/ΔX

 1             5               xxxxxx              Exponential because [ ΔY/ΔX ]          

 2            11              11 - 5 = 6            increases at the fastest rate out of all

 3           29             29 - 11 = 18         functions.

 4           83             83 - 29 = 54

 5           245          254 - 83 = 171

 6           731           731 - 254 = 477

Table B:

 X            Y                 ΔY/ΔX            Δ^2Y/ΔX^2          

 0             5                 xxxxxx              xxx             Quadratic because

 1              7                 7 - 5 = 2            xxx            Δ^2Y/ΔX^2 is a constant

 2             13               13 - 7 = 6           6-2 = 4       for all quadratic functions

 3             23              23 - 13 = 10       10-6 = 4

 4             37              37 - 23 = 14       14-10 = 4

 5             55             55 - 37 = 18        18-14 = 4

Table C:

 X            Y                 ΔY/ΔX                      

 3             20               xxxxxx                 Linear because

 6             18                 2 / 3                    ΔY/ΔX is a constant

 9             16                 2 / 3                   for all linear functions

 15            12                 2 / 3      

 27            4                  8/12 = 2/3      

 39           -4                  8/12 = 2/3

Explain why any of the four operations placed between two terms 5 and -3 sqrt (8) will result in an irrational number
Gnoma [55]

Sum/difference:

Let

x = 5 + (-3\sqrt{8}) = 5-3\sqrt{8}

This means that

3\sqrt{8} = 5-x \iff \sqrt{8} = \dfrac{5-x}{3}

Now, assume that x is rational. The sum/difference of two rational numbers is still rational (so 5-x is rational), and the division by 3 doesn't change this. So, you have that the square root of 8 equals a rational number, which is false. The mistake must have been supposing that x was rational, which proves that the sum/difference of the two given terms was irrational

Multiplication/division:

The logic is actually the same: if we multiply the two terms we get

x = -15\sqrt{8}

if again we assume x to be rational, we have

\sqrt{8} = -\dfrac{x}{15}

But if x is rational, so is -x/15, and again we come to a contradiction: we have the square root of 8 on one side, which is irrational, and -x/15 on the other, which is rational. So, again, x must have been irrational. You can prove the same claim for the division in a totally similar fashion.
