Evaluate the limit from the right side as x approaches −6
step 2
The expression x+6e2x becomes undefined as x approaches −6 from the right, since the denominator approaches 0
step 3
As x gets closer to −6 from the right, e2x approaches e−12, which is a positive constant
step 4
Since the numerator remains positive and the denominator approaches 0 from the positive side, the limit tends to +∞
Answer
limx→−6+x+6e2x=+∞
Key Concept
Limits involving a non-zero constant divided by an expression approaching zero
Explanation
As x approaches −6 from the right, the denominator of the fraction x+6e2x approaches zero, causing the value of the fraction to increase without bound. Hence, the limit is +∞.
