Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
alisha [4.7K]

Answer:

option A

f(x) = (x – 1)2 + 3

Step-by-step explanation:

Given in the question a function,

f(x) = 4 + x² – 2x

<h3>Step 1</h3>

f(x) = 4 + x² – 2x

here a = 1

        b = -2

        c = 4

<h3>Step 2</h3>

x = -b/2a

h = -(-2)/2(1)

h = 2/2

h = 1

Step 3

Find k

k = 4 + 1² – 2(1)

k = 3

Step 4

To convert a quadratic from y = ax² + bx + c form to vertex form,

y = a(x - h)²+ k

y = 1(x - 1)² + 3

y = (x - 1)² + 3

Can you divide the number 8,101,265,822,784 by 8 without using either long or short division?
LuckyWell [14K]
Yes. If we wanted to divide  104 by 8 we could write 104 as sum of multiples of 8 with which we are familiar:

104=80+24

then \frac{104}{8}= \frac{80+24}{8}= \frac{80}{8}+ \frac{24}{8}=10+3=13

We use the same procedure to divide the given number by 8:



First  We can "decompose" the number as a sum of multiples of 8 which we recognize easily. Then, divide each single one of them with 8.

That is 

 <span>8,101,265,822,784 = 8,000,000,000,000+100,000,000,000+1,000,000,000
</span>
+265,822,784

now decompose 265,822,784:

265,822,784=240,000,000+24,000,000+1,000,000+800,000+22,784

now decompose 22,784

22,784=16,000+6,784

decompose 6,784

6,784=6,400+384= 6,400+320+64


Thus:

 8,101,265,822,784 : 8 =(8,000,000,000,000+100,000,000,000+1,000,000,000+240,000,000
+24,000,000+1,000,000+800,000+16,000+6,400+320+64):8

=1,000,000,000,000+12,500,000,000+125,000,000+30,000,000+
3,000,000+125,000+100,000+2,000+800+40+8

=(1,000,000,000,000+12,500,000,000)+(125,000,000+30,000,000)
   + 3,227,848

=1,012,500,000,000+155,000,000+3,227,848

=1,012,655,000,000+3,227,848

=1,012,658,227,848
