What is the inverse of the function f(x) = 1/4x-12?
Marrrta [24]

Answer:

\huge\boxed{f^{-1}(x)=4x+48}

Step-by-step explanation:

In order to find the inverse of a function, we need to follow a couple of steps.

  • Step 1: Write the function as y=mx+b
  • Step 2: Swap all x and y values
  • Step 3: Solve for y
  • Step 4: Replace y with f^{-1}(x)

We can follow these steps to find the inverse of this function.

Step 1: We can just replace the f(x) with y, making our function y=\frac{1}{4}x-12.

Step 2: We can swap where the x and y values are, making our equation

x = \frac{1}{4}y-12

Step 3: We can now solve for y.

  • x = \frac{1}{4}y-12
  • x + 12 = \frac{1}{4}x
  • 4x+48 =y

We now have the function as y = 4x+48.

Step 4: We can now replace the y with f^{-1}(x).

f^{-1}(x) =4x+48

Therefore the inverse of f(x) = \frac{1}{4}x-12 is f^{-1}(x) =4x+48.

Hope this helped!

Find a in degrees.<br> 3<br> V58<br> 7 <br> ?
s344n2d4d5 [400]

Answer:

  23.20°

Step-by-step explanation:

All three sides of this right triangle are given, so the acute angle of interest can be found using any of the inverse trig functions.

<h3>Trig relation</h3>

The tangent of the angle is the ratio of opposite and adjacent sides:

  Tan = Opposite/Adjacent

Here, that means ...

  tan(α) = 3/7

To find the value of α, we need to use the inverse tangent function, also called the arctangent function.

  α = arctan(3/7) ≈ 23.19859°

  α≈ 23.20°
