Utiliza el criterio de la segunda derivada para hallar las coordenadas del punto máximo relativo \( y \) del punto mínimo relativo de la función \( f(x)=x^{3}-9 x^{2}+24 x-14 \). Dado que \( f^{\prime \prime}(2) \) es menor que cero, entonces en \( x=2 \) hay un minimo relativo o local cuyas coordenadas son \( P(2,6) \) Dado que \( f^{\prime \prime}(2) \) es mayor que cero, entonces en \( x=2 \) hay un mínimo relativo o local cuyas coordenadas son \( P(2,14) \) Dado que \( f \) "( 2 ) es menor que cero, entonces en \( x=2 \) hay un máximo relativo o local cuyas coordenadas son \( P(2,6) \) Dado que \( f \) " \( (2) \) es mayor que cero, entonces en \( x=2 \) hay un máximo relativo o local cuyas coordenadas son \( P(2,14) \)

5. a) The function \( f(x)=x \sin (1 / x) \) is continuous for all \( x \neq 0 \).
