Which of the following sets of numbers could be the lengths of the sides of a triangle?
a. 7.4 cm, 10.5 cm, 15.5 cm
b. 10.5 cm, 15.5 cm, 4.5 cm
c. 7.4 cm, 15.5 cm, 23 cm
d. 7.4 cm, 10.5 cm, 19.5 cm

  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.

is should be y = 5x
