Question

Find the f(√2) if f(x) = x2 + √2x + 1​

Answer 1

Answer:

Given that :-

f(√2)

f(x) = x² + √2x + 1

f(√2) = (√2)² + √2 × √2 + 1

= 2 + 2 + 1

= 5

Answer 2

Hii...

Here's your answer...

$f(x) \: \: = \: {x}^{2} + \sqrt{2} x + 1 \\ f( \sqrt{2} ) = \: (\sqrt{2} )^{2} + \sqrt{2} \times \sqrt{2} + 1 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 + 2 + 1 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 5$

Hope it'll help you...

Thanks...
