Colin invests £980 into his bank account. He receives 2.1% per year simple interest. How
much will Colin have after 4 years? Give your answer to the nearest penny where appropriate.

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

  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.
