To find an inverse function:
1. Write the function.
2. Replace f(x) with y.
3. Switch x and y.
4. Solve for y.
5. Replace y with

Now let's follow the steps above and do it.
1. f(x) = 4x
2. y = 4x
3. x = 4y
4. y = x/4
5.
The answer simplified is 6
Sir you posted question and answer? or are providing examples of preferred format?
Answer:


Step-by-step explanation:
we are given
speed =8 mph
time = 6 hours
so, we have

now, we can find distance
distance = (speed)*(time)


so, we have

so, our range for x and y can be


C. million or 500,000,000
d.thousands or 30,000
and the first one is good and the second one for the million you wrote all the zeros right so it should look like 80,000,000
