Elden [556K]3 years ago
4 0

Answer:

  f^-1(x) = (x -2)/3

Step-by-step explanation:

To find the inverse function, swap x and y, then solve for y.

  y = 3x +2 . . . . given function

  x = 3y +2 . . . . inverse relation

  x -2 = 3y . . . . subtract 2

  (x -2)/3 = y . . . divide by 3

f^-1(x) = (x -2)/3 . . . . in functional form

What is the volume of a rectangular prism when the measures are multiplied by 4?
koban [17]

Answer: A. 3072 cm³

Step-by-step explanation:

The formula for determining the volume of a rectangular prism is expressed as

Volume = length × width × height

Looking at the diagram,

Length = 6 cm

Width = 4 cm

Height = 2 cm

When the measures are multiplied by 4, then

Length = 6 × 4 = 24 cm

Width = 4 × 4 = 16 cm

Height = 2 × 4 = 8 cm

Therefore,

Volume = 24 × 16 × 8 = 3072 cm³
