Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
Then,
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
which yields
Answer: 1 bulb
Step-by-step explanation:
Using the proportion of flawed bulbs in the first scenario, you can get the number of flawed bulbs in the other bath.
