Which expression correctly represents “twice the sum of four and a number”?
2 (4 + n)
2 (4 n)
2 (4) + n
2 + (4 n)

The first one 2(4+n)

Step-by-step explanation:

Twice =2*

sum of 4 and a number =(4+n)

so

2*(4+n)

  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.
