Answer:
The correct option is 2.
Step-by-step explanation:
The given function is
Where, a and b are positive numbers.
The given function is the slope intercept form of a linear function. Where a is the slope and b is y-intercept.
Since slope is positive therefore function approaches to infinity as x approaches to infinity and function approaches to negative infinity as x approaches to negative infinity.
It is also proved by using limits.
Apply limits.
Similarly,
Apply limits.
Therefore option 2 is correct.
