Question

Suppose x x represents the value of some varying quantity. As the value of x x varies from 3.5 to 8.

What is the change in the value of x x?

Answer 1

Answer: The change in the value of x would be :
`\Delta x=4.5` .

Explanation:

We know that if y represents the value of some varying quantity, then as the value of y varies from p to q.

The change in the value of y is given by :-

`\Delta y=q-p` [Next value - previous value]

Given : x represents the value of some varying quantity.

So , As the value of x varies from 3.5 to 8.

The change in the value of x is given by :-

`\Delta x=8-3.5=4.5`

Hence, the change in the value of x would be :
`\Delta x=4.5`
