Find f-1(x), if f(x) = 3x – 6. Justify your
Sergio039 [100]
Answer: 1/3 (x + 6)

Explanation: given f(x) = 3x - 6.
Let y = f(x) and so y = 3x - 6.
Trade places between x and y.
x = 3y - 6
Solve for y
x + 6 = 3y
y = x + 6/3
Now the new y is the inverse and so y = f-1(x)
f-1(x) = 1/3(x + 6)

How to calculate the percentage?
miv72 [106K]

\:  \:  \:  \:  \:

  1. <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>

  1. <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
  2. <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
  3. <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>

  • <u>Multiply by 100 and add a percentage </u><u>sign</u>
  • <u>0.876 = 0.876 * 100 = 87.6%</u>

<h2><u>hope</u><u> it</u><u> helps</u></h2>
