Step 1.1

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $\infty$ .

$lim_{x \to \infty} 4 + lim_{x \to \infty} \frac{3}{x}$

Step 1.2

Evaluate the limit of $4$ which is constant as $x$ approaches $\infty$ .

$4 + lim_{x \to \infty} \frac{3}{x}$

Step 1.3

Move the term $3$ outside of the limit because it is constant with respect to $x$ .

$4 + 3 lim_{x \to \infty} \frac{1}{x}$

Step 2

Since its numerator approaches a real number while its denominator is unbounded, the fraction $\frac{1}{x}$ approaches $0$ .

$4 + 3 \cdot 0$
