Answer 1

well replace y with f(x)

Answer 2

i dont understand

Answer 3

ok.... here is an equation

y = x

written using function notation its

f(x) = x

Answer 4

f(x) is another way of saying y, it's a function of x. Being y is dependent on x

im so lost

Answer 6

y = f(x)

Answer 9

well you are missing the independent variable... x

Answer 10

omfg -.-

Answer 11

-2/3 has an x :P

f(x) = -2/3x + 400 *

without the x you can't really do anything

Answer 12

so thats the answer?

Answer 13

Yeah o.0 you're just replacing y with the function notation -- f(x)
