Identify highest power: Identify the highest power of x in the numerator and denominator.In the numerator, it's x2. In the denominator, it's e19x.
Neglect terms with x: Since e19x grows much faster than any power of x, the terms with x in the denominator become negligible as x approaches infinity.So, we can ignore the 2x term in the denominator.
Compare coefficients: Now, we look at the coefficients of the highest powers. The limit becomes the coefficient of x2 in the numerator divided by the coefficient of e19x in the denominator as x approaches infinity.
Calculate the limit: The coefficient of x2 is 2, and the coefficient of e19x is 3. So, the limit is 32.
