The inverse of f(x) would be f(x) = 2 - 8.
We can find this by taking the original equation and switching the x and f(x). Once we do this, we solve for the f(x) in its new place and that is the inverse equation. It is taken step by step for you below.
Take the original.
f(x) =
Now switch the x and f(x)
x =
Now square both sides.
=
f(x) + 4
Now subtract 4 from both sides.
- 4 =
f(x)
Now multiply both sides by 2.
2 - 8 = f(x)
And once you've returned to f(x) =, then you have your inverse.
Answer:
About 300 of every 1,000 cars assembled should have one or more defects
Step-by-step explanation:
From the sample of 100 cars, we can estimate the total number of defective cars, using a rule of three.
In this question:
For each 100 cars, 30 defective.
How many defective for 1000?
100 cars - 30 defective
1000 cars - x defective
Simplifying by 100
About 300 of every 1,000 cars assembled should have one or more defects
