Answer:
The graph approaches –3 as x approaches infinity. Option a is correct.
Step-by-step explanation:
The given function is
We have to find value of function as x approaches infinity. Take limit both sides as x approaches to infinity.
Taking x common from the denominator.
Cancel out common factor x.
Apply limits.
Therefore the graph approaches –3 as x approaches infinity.
For when x=2, You get 14.
For when x=3, You get 11.
Therefore, x=2 gives a bigger value.
His average speed for the first trip is 43 mph
Since Brian's average speed is x and he travels the first part for 215 miles in time t.
So, his distance d = xt
Also, the travels 75 more miles at a speed of 15 mph.
Since distance = speed time, the time he takes to cover this distance is
t' = distance/speed = 75 mi/15 mph = 5 hours
Since he covers both distances in the same time, we have that t = t' = 5 hours.
So, his average speed for the first trip x = d/t
= 215 mi/5 h
= 43 mph
His average speed for the first trip is 43 mph
