Answer 2

so read it off the table

Answer 3

so 4?

Answer 4

No f(5) = 4

Answer 5

I'm confused

Answer 6

what is the value of f(y) when y = 6?

Answer 7

3

Answer 8

- check the table

Answer 9

is it 3 because you multiply it to get 6?

Answer 10

NO
its 3 because it is given as 3 in the table.

Answer 11

ohhhh sorry, i get it

Answer 12

i know what i was doing wrong, i kept looking at the 6 in the f(y) column

Answer 13

i wasn't thinking oops

Answer 14

lets take a simple function

f(y) = 2y

when y = 2 , f(y) = 2*2 = 4
and we say that f(2) = 4

In the same way f(3) = 2*3 = 6


get it?

Answer 15

I get it, thank you.

Answer 16

Answer 17
