What is the inverse of the function below? f(x)= x/4 -2

Answers

Answer 1

Answer:

The inverse of function f(x) = x/4 - 2 is:

f^(-1)(x) = 4(x + 2).

Option C is the correct answer.

We have,

To find the inverse of the function f(x) = x/4 - 2, we can follow these steps:

Step 1: Replace f(x) with y: y = x/4 - 2.

Step 2: Swap the variables x and y: x = y/4 - 2.

Step 3: Solve the equation for y.

Let's start by isolating y:

x = y/4 - 2

x + 2 = y/4 (Adding 2 to both sides)

4(x + 2) = y (Multiplying both sides by 4)

So, the inversefunction is y = 4(x + 2).

However, it's common to write the inversefunction with the variable x instead of y.

Therefore,

The inverse of function f(x) = x/4 - 2 is:

f^(-1)(x) = 4(x + 2).

What do you suppose a decimal value for a day in the month means

Answers

It would be 0 till the end of the month because that’s where it started from and when it’s going to end

Say you’re on the 14th day of a month, and it’s noon on the 14th. I’d assume a decimal place after the day would mean how far you are through that day

Thx :)

Answers

the answer is 41/50 because if you solve it, 41/50=0.82. Since it is a percentage, you multiply the answer, 0.82, by 100 and you get 82. hope that helped :)
