Question

Is `c= e/-4` a direct variation, inverse variation, or neither?

Answer 1

See Below.

Explanation:

I'm considering `e` as a variable.

As We have `c = e/-4`,

We can Write this as

`c/e = -1/4` [Dividing both sides by `e`]

As `c/e` is equal to a constant, we can say `c prop e` or, `c` and `e` are in

direct variation.

But, This results in a confusing situation.

If we take `c = 1`, we get, `e = -4.`

But if we put `c = 2`, we get, `e = -8`.

So, Actually, If we increase `c`, e is decreasing, and again, with the same ratio, `-1/4`.

So, Defintion of Variation and The Results we are getting are contradicting each other.

But still, The graph of the relation shows it is direct.

graph{y = (x/(-4)) [-10, 10, -5, 5]}

I don't think this is a variation. But This is my opinion. I need consultations.

Answer 2

A constant thus neither

Explanation:

`e` is a constant `e~~2.71828.... ->2.72` to 2 decimal places

Thus `e/(-4)` is also a constant
