Question 10:
Given a function \(f\left(x\right)=\sqrt{5x-1}\).
To compare: \(f\left(1\right)..........f\left(\frac{1}{5}\right)\) .
\(f\left(1\right)=\sqrt{5.1-1}=\sqrt{5-1}=\sqrt{4}=2\); \(f\left(\frac{1}{5}\right)=\sqrt{5.\frac{1}{5}-1}=\sqrt{1-1}=\sqrt{0}=0\)
Vì 2 > 0 nên \(f\left(1\right)>f\left(\frac{1}{5}\right)\)
Given 𝐴 = 9𝑥2 + 8 − 12𝑥 and 𝐵 = 2.
To compare: 𝐴 …𝐵.
We have : \(A=\)\(9x^2+8-12\)
=\(\left[\left(3x\right)^2-2.3x.2+4\right]+4\)
\(=\left(3x-2\right)^2+4\ge4\)(first)
But \(B=2\)(2)
From (1) and (2)
\(\Rightarrow A>B\)
