If f(x) varies directly with x and f(x) = 24 when x = –4, then what is f(x) when x = 12?

Answer 1

Im so lost I don't get it plz help :/

Answer 2

Well first let's find the ratio of f(x).

We are given:

f(x) = 24
x = -4

We can divide these two and then use them to find out what f(x) is when x is 12.

Answer 3

Are you catching on?

Answer 4
