¿Cómo se hace una tabla de valores sobre "f ( x ) = x 2 4 − 3 x + 5 x = 0 , 2 , 4 , 6 , 8 , 1 0 , 1 2 f(x)=x24-3x+5 x= 0, 2, 4, 6, 8, 10, 12" de función cuadrática?

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

tube or goog would be a great resource to with that question

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
