Para determinar el límite \( \lim _{x \rightarrow 1}(5 x^{2}+9 x) \), simplemente sustituimos \( x \) por 1 en la expresión. Así que tenemos: \[ 5(1)^{2} + 9(1) = 5(1) + 9 = 5 + 9 = 14. \] Por lo tanto, el límite es 14. Ahora, podría ser útil recordar que este tipo de límites se pueden evaluar de manera directa cuando estamos tratando con polinomios, ya que son continuos en todos los puntos de su dominio. Esto significa que no hay necesidad de preocuparse por indeterminaciones, ¡solo sustituyes y resuelves!
