If it has x intercepts at r1,r2,r3 then the factored form is
f(x)=a(x-r1)(x-r2)(x-r3)
where  a is a constant not equal to 0
so
intercepts of -2,0, 1

f(x)=a(x-(-2))(x-0)(x-1)
f(x)=a(x+2)(x)(x-1)
passes through the point (2,16)
find a buy subsituting the point (2,16) into it

16=a(2+2)(2)(2-1)
16=a(4)(2)(1)
16=8a
2=a
the function is
f(x)=2(x+2)(x)(x-1)

U1.000 = 2 + ( 1.000 - 1 ) 6

U1.000 = 2 + ( 999 ) 6

Roberto took a sample of 5 recent matches for his favorite soccer team. Here is how many goals the team scored in each match: 0,
kap26 [50]

<em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>

The mean of the data is also known as average.

Given the set of data 0, 2, 1, 2, 5

Mean = 0+2+1+2+5/5

Mean = 10/5

Mean = 2.0

To get the standard deviation, we will use the SD formula as shown:

\sigma=\sqrt{\frac{\sum (x-\overline x)^2}{N} }

\sigma =\sqrt{ \frac{(0-2)^2+(2-2)^2+(1-2)^2+(2-2)^2+(5-2)^2}{5}}\\ \sigma = \sqrt{\frac{4+0+1+0+9}{5}} \\\sigma =   \sqrt{\frac{14}{5} }\\\sigma =  1.673

Comparing this with Roberto's calculation, we can see that <em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>
