As áreas de diferentes quadrados da fachada de um prédio com 20 andares formam uma progressão aritmética de razão 3 m². Sabendo-se que a área do primeiro quadrado da sequência é igual a 54 m², qual é a medida do lado do décimo quadrado da sequência? a) 1 m
b) 2 m
c) 3 m
d) 6 m
e) 9 m

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
