4. De las siguientes funciones cuadráticas determinar: cortes eje x , corte eje \( y \), punto máximo o mínimo, dominio y rango, grafica. a. \( f(x)=3 x^{2}-8 x+2 \) b. \( f(x)=-2 x^{2}-6 x+3 \) c. \( h(x)=-x^{2}+4 x-6 \)

\( \quad A=\left\{\frac{1}{3}, \frac{5}{4}, \frac{11}{2}, \frac{7}{8}, \frac{25}{3}\right\} \) \[ B=\left\{\frac{1}{4}, \frac{35}{40}, \frac{15}{12}, \frac{11}{3}, \frac{25}{4}\right\} \] \( C=\{x \in \mathrm{Q} \mid x<1\} \) \( D=\{x \in \mathrm{Q} \mid x>2\} \) Determina: a. \( A \cap B \) b. \( A \cup B \) c. \( A-B \) d. \( (A \cup B) \cap C \) e. \( (A \cup B) \cap D \)

Which expression best estimates \( 6 \frac{3}{4}+1 \frac{2}{3} \) ? \( 7+2 \) \( 6+1 \) \( 8+3 \) \( 3+2 \) \( 0^{7} \)
