Answer 1

rewrite this please. it's kinda unclear. also f(x) can be simplified to f(x)= 1.2x

so their it is

Answer 5

Ah that makes sense. Thank you for clarifying that.

Answer 6

lol sorry correction

Answer 7

Ooooh the x is a power I see. That makes much more sense xD

Answer 8

can you help me ... actually break it down

Answer 9

I'll try. Well first we multiply 3 by 4 which is 1.2

Answer 10

The power is 6 so we multiply 1.2 by itslelf 6 times.
