\(G=17-\left|3x-2\right|\le17\forall x\)
Dấu '=' xảy ra khi x=2/3
\(K=17-\left|3x-2\right|-\left(3x-2\right)^{2020}< =17\forall x\)
Dấu '=' xảy ra khi x=2/3
\(G=17-\left|3x-2\right|\le17\forall x\)
Dấu "=" xảy ra\(\Leftrightarrow x=\dfrac{2}{3}\)
Vậy \(G_{max}=17\Leftrightarrow x=\dfrac{2}{3}\)
\(K=17-\left|3x-2\right|-\left(2-3x\right)^{2020}\le17\)
Dấu "=" xảy ra\(\Leftrightarrow x=\dfrac{2}{3}\)
Vậy \(K_{max}=17\Leftrightarrow x=\dfrac{2}{3}\)
\(G=-\left|3x-2\right|+17\le17\)Dấu ''='' xảy ra khi x = 2/3
