Answer 1

Well first of all, let's define what an integer is...

Integers are numbers such as -2, -1, 0, 1, 2 etc etc.

------

If f(5)=12,

f(6)=0.3*f(6-1)

= 0.3*f(5)

= 0.3*12

= 3/10 * 12

= 36/10

= 3.6

We now know that f(6)=3.6

Now:

f(7)=0.3*f(7-1)

= 0.3*f(6)

= 0.3*3.6

= (3/10) * (36/10)

= 108/100

= 1.08

Answer:

f(7)=1.08
