The range of this function is y is equal to all real numbers such that y 0.
The definition of an absolute value is that it is always positive. Therefore, we know there can never be a negative value of y. This means that the lowest a function can go is to 0. Since there is no restrictions on how high it can go, y is able to go from 0 to infinity.
Hello.
Let's call the initial speed 'x'. When driving at that speed, Jeremy's father takes 20 minutes to arrive to the school. When driving 18 mph faster (x + 18), he gets there in 12 minutes. Therefore:
20 - x
12 - x + 18
As they're inversely proportional:
12 - x
20 - x + 18
That means that the initial speed is of 27mph. Since we have the time and the speed, we can find the distance:
Average Speed = Total Distance Travelled / Time Interval
20 minutes = 0.33h
Hope I helped and good luck.
