Answer:
Step-by-step explanation:
The inverse of a function is when the x and y are swapped. So the first step is to write f(x) as y and then swap the x and y
Original Equation:
write f(x) as y (since that's what it represents)
Swap x and y
Square both sides
Add 1 to both sides
So this gives you the equation:
Let's solve ~
Therefore, Option D is correct ~
Answer: Either or
==================================================
Explanation:
w = width
w-4 = length since it is 4 less than the width
Multiply the length and width to get the area of the rectangle.
area = length*width
area =
area =
area =
In the last step, I used the distributive property.
Either expression mentioned above is valid for the area. If you had to pick only one, I'd go for
