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

Bad White [126]

Answer:

(a) The product of the sum of a and b and their difference.

(a+b)\times{(a-b)}\\=a^2-b^2

(b) The tripled product of 6a and b².

3(6a\times{b^2})\\=3(6ab^2)\\=18ab^2

(c) The difference of the squares of 2m and 7n.

(2m)^2-(7n)^2\\=4m^2-49n^2

A parabola has a vertex at (0,0). The equation for the directrix of the parabola is x = –4. In which direction does the parabola
zaharov [31]

The parabola with vertex at (0,0) and directrix at x=-4, will open towards the right.

<h3>What is a directrix?</h3>

A parabola is a collection of points on a plane that are all at the same distance from a particular point and line. The point is called the focus of the parabola while the line is called the directrix. The directrix is perpendicular to a parabola's axis of symmetry and does not contact it.

As we know that the directrix is perpendicular to the axis of the parabola, now since the directrix is at x=-4, the parabola will be horizontal and will be opening either towards the left or the right.

As it is given that the vertex of the parabola is at (0,0) and we know that the parabola can not touch the directrix, therefore, the parabola's vertex will be at (0,0) and will open towards the right side. As shown below.

Hence, the parabola with vertex at (0,0) and directrix at x=-4, will open towards the right.
