Answer:
₹663
Step-by-step explanation:
The ratio of the tax to the total is ...
13%/(100%+13%) = VAT/5763
VAT = 5763(0.13/1.13) = 663
The value added tax is ₹663.
We will see that f'(x) > 0, which means that f(x) is an increasing function.
<h3>
How to prove that the function is increasing?</h3>
For any function f(x), if f'(x) > 0, then f(x) is increasing for any value of x.
Here we have the cubic function:
f(x) = x³ + 4x
If we differentiate this, we get:
f'(x) = df(x)/dx = 3x² + 4.
And notice that x² is always positive, then f'(x) > 0, which means that f(x) is an increasing function.
