4 0

Answer:

Step-by-step explanation:

The finite set is  in which we can count the elements which has finite number of elements

option 1 is not correct because we can not count the whole numbers they could extended upto infinite.

Option 2 is correct that is finite because condition is given that is natural numbers less than 100,000.

Option 3 is finite because we can count all letters of the alphabet.

Option 4 is not finite because all odd numbers can be extended upto infinity.

Option 5 is correct that is finite because world's population will be a finite number.

Option 6 is finite because it is empty set which is finite.

Write 3x^2-18x-6 in vertex form
Vedmedyk [2.9K]
The standard form of a quadratic equation is \displaystyle{ y=ax^2+bx+c, while the vertex form is:

                      y=a(x-h)^2+k, where (h, k) is the vertex of the parabola.

What we want is to write \displaystyle{ y=3x^2-18x-6 as y=a(x-h)^2+k

First, we note that all the three terms have a factor of 3, so we factorize it and write:

\displaystyle{ y=3(x^2-6x-2).


Second, we notice that x^2-6x are the terms produced by (x-3)^2=x^2-6x+9, without the 9. So we can write:

x^2-6x=(x-3)^2-9, and substituting in \displaystyle{ y=3(x^2-6x-2) we have:

\displaystyle{ y=3(x^2-6x-2)=3[(x-3)^2-9-2]=3[(x-3)^2-11].

Finally, distributing 3 over the two terms in the brackets we have:

y=3[x-3]^2-33.


Answer: y=3(x-3)^2-33
