In a certain county, the number of charter schools is 4 less than twice the number of alternative schools. we know that there are 48 charter schools in the county. how many alternative schools are in the county? 52 22 36 26

  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.
