Question

What happens to the value of the expression 150-j150−j150, minus, j as jjj decreases?

Answer 1

The value of the expression increases as j decreases

Explanation:

Let
`f(j) = 150 - j150 - j150`

`f(j) = 150 - j300`

As j decreases, the value of j300 decreases (i.e the farther j300 is from 150). Due to the wider gap between 150 and j300, the value of f(j) increases.

For example:

When j = 1, f(j) = 150 - (300*1) = -150

When j = 0.5, f(j) = 150 - (300*0.5) = 0

When j = 0. f(j) = 150 - (300*0) = 150

It is obvious from the analogy above that the expression 150-j150−j150 increases as j decreases
