Determine the domain and range for the inverse of F (x)=1/2x -3
1 answer:
The inverse function for f(x) is still going to be a linear function. A linear function has no restrictions on domain and range, therefore the domain and range for the inverse of F(x) is going to be all real numbers or (-infinity,infinity). Hope this helps!!!

Given:
Consider the complete question is "A speed walker covered mi in
hour. How far will he walk in 3/4 hours if he walks twice as fast?"
A speed walker covered mi in
hour.
To find:
Distance covered by him if in 3/4 hour if he walks twice as fast.
Solution:
We have,
It means a speed walker covered mi in
hour.
If the speed is twice then he can cover double distance is same time.
Distance covered by him if in 3/4 hour if he walks twice as fast is
Therefore, distance covered by him is 9 mi.
A 33 gram sample has k value of .1124
(Actually I think the problem SHOULD be worded: A 33 gram sample has k value of -.1124/days)
See attached graphic:
Half-Life = ln (.5) / k
Half-Life = -.693147 / -.1124/days
Half-Life = <span> <span> <span> 6.1667882562 </span> </span> </span> days
