A bag contains 10 discs. Each disc is labelled with a different number from 1 to 10.
A disc is chosen from the bag at random.
Write down the probability that the chosen disc is the number 3

dont understand

step-by-step explanation:

  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.
