Think about how to use the interactive tool to form an expression equivalent to –x + ( –3x) + 12 – 9. An equivalent expression is
__ + 3

a

Step-by-step explanation:

i did the question

its a or -4x

Step-by-step explanation:

just did the test

  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.
