What is the advantage of using function notation instead of using y?

The advantage of using function notation is that you can see the input and the output in the answer. For Example: if f(x)=2x + 1 then f(3)=7

<h2>Question:-</h2>

If a = 6 - $\sqrt{35}$ , find the value of a² + $\frac{1}{a²}$

<h2>Solution:-</h2>

a = 6 - $\sqrt{35}$ (Given)

Now, first of all we have to find the value of $\frac{1}{a}$ .

So, $\frac{1}{a}$ = $\frac{1}{6 \: - \: \sqrt{35}}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{(6 \: - \: \sqrt{35})(6 \: + \: \sqrt{35})}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{(6)² \: - \: (\sqrt{35})²}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{36 \: - \: 35}$ $(\because \sqrt{35} \: × \: \sqrt{35} \: = \: 35)$

$\frac{1}{a}$ = $\frac{6 \: + \: \sqrt{35}}{1}$

$\frac{1}{a}$ = 6 + $\sqrt{35}$

Now, we have to find the value of a² + $\frac{1}{a²}$

So, a² + $\frac{1}{a²}$ = $(a \: + \frac{1}{a})²$ - 2.a. $\frac{1}{a}$

a² + $\frac{1}{a²}$ = $(6 \: - \sqrt{35} \: + \: 6 \: + \sqrt{35})²$ - 2

a² + $\frac{1}{a²}$ = (12)² - 2

a² + $\frac{1}{a²}$ = 144 - 2

a² + $\frac{1}{a²}$ = 142

The value of a² + $\frac{1}{a²}$ is 142. [Answer]
