Final answer:
To find the limit of the given function as x approaches infinity, substitute infinity into the function and simplify. The limit is 0.
Step-by-step explanation:
To find the limit of a function, we substitute the given value into the function and simplify as much as possible. In this case, we want to find the limit of -3/(4x + 9) as x approaches a certain value. Let's say we want to find the limit as x approaches infinity. We substitute infinity into the function and simplify:
lim (-3/(4x + 9)) as x->∞ = -3/(4∞ + 9) = -3/(∞ + 9) = -3/∞ = 0.
So, the limit of the function as x approaches infinity is 0.
