Which of the following describes the polynomial function?
klemol [59]
Your image is cropped, so I can’t see the options to choose from but this would work too:

=> (x-2)(x-5)(x-7)
=> (x^2 -5x -2x +10)(x-7)
=> (x^2 -7x +10)(x-7)
=> (x^3 -21x^2 +10x -7x^2 + 49x -70)

=> x^3 -28x^2 + 59x -70

The following is true:

* the polynomial has a positive leading coefficient.

* the polynomial has a domain of x = (-oo, oo)

Which describes a number that cannot be irrational?
VMariaS [17]

Answer:

A number that cannot be irrational is:

A number that cannot be written as the ratio of two integers

Step-by-step explanation:

Irrational numbers can be defined as those numbers which cannot be written as in a form of Fraction (Ration of two integers).

E.g if we consider the value of constant pi

π = 3.14159265...................

and it goes on, that why we cannot write it in a form of simple fraction.

Another example of irrational number is under root of 2

√2 = 1.41421356..................

Hence, it also cannot be written as a simple fraction.

However, a number which can be written as a ratio of two integers is a rational number. e.g

2/5 , 1/4 etc

As a rational number can never be an irration number, so statement 1 is correct
