Step-by-step explanation:-2 + 2 = 0 + 2= 2 + 2 = 4

The function table is solved and the quadratic equation is f ( x ) = -3x²

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

f ( x ) = -3x²

when x = -2

f ( -2 ) = -3 ( -2 )²

f ( -2 ) = -12

And , when x = 0

f ( 0 ) = 0

when x = 2

f ( 2 ) = -12

when x = 4

f ( 4 ) = -48

Hence , the function table is f ( x ) = { -12 , 0 , -12 , -48 }

Answer:

z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean.

Step-by-step explanation:

The formula for z score is given as:

z = (x-μ)/σ,

where

x is the raw score = 9.7%

μ is the population mean = 13.26%

σ is the population standard deviation = 1.67%

z = z score or standardize score

Hence,

z = 9.7 - 13.26/1.67

z = -2.13174

Approximately z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean
