The set of all numbers less than or equal to -8 or greater than or equal to 2.
tatiyna

The set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}

<h3>The set of numbers</h3>

From the question, we are to write the set of numbers l<u>ess than or equal</u> to -8 or<u> greater than or equal</u> to 2

Let x represent the set of the numbers

If a number is less than or equal to -8

Then,

-8 is greater than or equal to the number

That is,

-8 ≥ x

If a number is greater than or equal to 2

Then,

x ≥ 2

Thus, the set of all the numbers is

-8 ≥ x ≥ 2

Hence, the set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}

Points Lying on the undefined curve are

x :   0     1      2     3      4

f(x): 3    7     29    87    199

Plotting the points on the coordinate plane

As you will see, the value of x increases , value of y increases .

It is not linear, because slope between two points is not same.

Neither quadratic nor cubic  , it is not cutting x axis .

So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.

So, option (D) Exponential ,Function word is the right word Describing these points.

What does the algebraic representation (x,y) → (-x, y) represent?
torisob [31]

Answer:

The given algebraic representation (x,y) → (-x, y) represents the reflection of a point (x, y) across the y-axis.

Step-by-step explanation:

We know that when a point P(x, y) is reflected across the y-axis, the x-coordinate changes/reverses its sign, but the y-coordinate stays the same.

Thus, the rule of reflection of a point P(x, y) across y-xis is:

P(x, y) → P'(-x, y)

For example, if a point A(1, 2) is reflected across the y-axis, the coordinates of the image A' of the point A(1, 2) will be:

A(1, 2)  → A'(-1, y)

In our case, we are given the  algebraic representation

(x,y) → (-x, y)

Here:

  • The x-coordinate changes/reverses its sign
  • The y-coordinate stays the same.

Thus, the given algebraic representation (x,y) → (-x, y) represents the reflection of a point (x, y) across the y-axis.
