Suppose f(x) - x = 2/ x. Fincd f(- 3) a
- 1/3
b
1/3
c
5/3
d
- 5/3

To find the mode you need to check the number which is more often repeated in the set than the other.But as you can see here there is no number which is repeated more often than the other everyone is repeated once,so in this case  we say that the set of data values has no mode.

To find the the range of the set of data you need to first place the numbers in ascending order (as it is already in) and then find the greatest and the smallest number and subtract them.

Range :

10,20,30,40,50,60,70,80,90,100,110,120,130,140,150.

Greatest number = 150.

Smallest number = 10.

Subtract = 150-10 = 140.
