The inverse is y = x/2 - 4
Steps involved are -
- replace f(x) with y: y = 2(x + 4)
- Then switch y and x: x = 2(y + 4)
- Finally make y the subject:
- x = 2(y + 4)
- x/2 = y + 4 (divide by 2)
- x/2 - 4 = y (subtract 4)
- So, the inverse is y = x/2 - 4
<h3>What is the formula for inverse function?</h3>
- In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
- The inverse of f exists if and only if f is bijective.
- f-1(y) = y/2 = x, is the inverse of f(x).

Answer:
the top 3
Step-by-step explanation:
Answer: 1,180 meters.
Step-by-step explanation:
Hi, to answer this question we have to subtract Terri's distance from the school (1.54) to Kim's distance from the school (2.72)
Mathematically speaking:
2.72 km - 1.54km = 1.18 km
Since the answer must be expressed in meters.
1000 meters = 1 kilometer
1.18 km x 1000 m/km = 1,180 meters.

Answer:
Move decimal points in 726.02, 3 points in the left direction
Step-by-step explanation:
Given
Quotient of 726.02 and 1000
This is represented as:
The denominator 1000 has 3 zeros.
This implies that the decimal points will be moved in the left direction by 3 points.
So:
