A function f has the following verbal description: multiply by 3, add 5, and
STALIN [3.7K]

Regarding the functions in this problem, it is found that:

a) The verbal description of the inverse is: Take the third root, subtract by 5 and divide by 3.

b) The formulas are:

  • f(x) = (3x + 5)³.
  • f^{-1}(x) = \frac{\sqrt[3]{x} - 5}{3}

c) The compositions result in x, hence they are inverses.

<h3>How to obtain the inverse function?</h3>

The original function is described as follows:

  • Multiply by 3: 3x.
  • Add 5: 3x + 5.
  • Take the third power: (3x + 5)³.

Hence the function is:

y = (3x + 5)³.

To obtain the inverse functions, we exchange x and y and then isolate y, hence:

x = (3y + 5)³

\sqrt[3]{x} = \sqrt[3]{(3y+5)^3}

3y + 5 = \sqrt[3]{x}

3y = \sqrt[3]{x} - 5

y = \frac{\sqrt[3]{x} - 5}{3}

f^{-1}(x) = \frac{\sqrt[3]{x} - 5}{3}

The verbal description of the inverse is:

  • Take the third root. sqrt[3](x).
  • Subtract by 5: sqrt[3](x) - 5.
  • Divide by 3.

The compositions are given as follows:

  • f(f^{-1}(x)) = f\left(\frac{\sqrt[3]{x} - 5}{3}\right) = \left(3\left(\frac{\sqrt[3]{x} - 5}{3}\right + 5)\right)^3 = (\sqrt[3]{x})^3 = x
  • f^{-1}(f(x)) = f^{-1}((3x + 5)^3) = \frac{\sqrt[3]{(3x + 5)^3} - 5}{3} = \frac{3x + 5 - 5}{3} = x

andrew11 [14]

Answer:

I'm going to calculate with sides 28 m

4,900 tiles used

Step-by-step explanation:

Area restaurant 28x28 = 784 m squared

each tile 40 cm = 0.4m

area of tile 0.4x0.4 =0.16

784/0.16 = 4,900

Find the measure of the angle indicated with a?, and enter the number only​
Reptile [31]

9514 1404 393

Answer:

  45°

Step-by-step explanation:

Arc YZ is the difference between the given arcs and 360°:

  126° +144° +YZ = 360°

  YZ = 360° -270° = 90°

The inscribed angle (?) is half the measure of the arc it intercepts:

  ? = 90°/2

  ? = 45°
