Answer:
The correct options are 3, 4 and 5.
Step-by-step explanation:
It is given that an air balloon begins it's decent to the ground at 1000 ft above the ground and falls at a rate of 50 ft per minute.
It means the initial height of air balloon is 1000. So, the y-intercept is (0,1000).
The ball falls at a rate of 50 ft per minute. So, the rate of change is
The height of balloon is defined as
Where, x is time in minutes.
The balloon will reach the ground when h(x)=0
Therefore the options 3, 4 and 5 are correct.
Step-by-step explanation:
Given function
To find an inverse for any given function, which is of the form , always swap
and
in the equation and try to get the form
. Now, swapping back
and
, we get the inverse function.
On swapping and
, we get
Swapping back and
, we get
This is the inverse function.
