How many zero pairs must be added to the function

f(x) = x - 10x - 4 in order to begin writing the function in

vertex form?

4

10

21

25

Option 4 - 25

Step-by-step explanation:

Given : Function

To find : How many zero pairs must be added to the function  in order to begin writing the function in  vertex form?

Solution :

The vertex form is

Let function

Applying completing the square,

Add and subtract square of half of the coefficient of x,

i.e.

Therefore, the zero pairs must be added to the function  in order to begin writing the function in  vertex form is 25.

So, Option 4 is correct.

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
