To say the least I have no idea why I'm in college algebra.I suck really bad!!!! I have a tutor that doesn't help. I need some help on getting examples for a real life example of a linear function.
I think the examples is so many that we do not even think of them. In 3d-graphics for example, you use a lot of vectors. In phisycs simulations, vectors for all sorts of things is essential. Your body weight is for example a linear function of your initial weight, how much food you eat and how much you drink, how much you burn and how much you sweat.
