Answer:
-1
Step-by-step explanation:
A function is represented by the following symbol f(x) where f(x) further represents y like this ,

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?
We can see in the graph when x = 5 the value of y is -1 to be exact so
f(5) = -1

Answer:
1 is 9 sq units
2 is 12
3 is 24cm^2
Step-by-step explanation:
assuming 
Then the column values for base five here are
5³ 5²

We can get 1 × 5³ = 125 → 219 - 125 = 94
We can get 3 × 5² = 75 → 94 - 75 = 19
We can get 3 x
→ 19 - 15 = 4
and 4 = 4 × 
Thus
= 
As a check
(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219
