3round 3.452 to one
decimal place

3.5

Step-by-step explanation:

3.452 rounded to one decimal place would eliminate numbers:

3.452

3.45

The .45 would then round to .5 as it's closer to .50 than .40

  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.
