Answer:

A

Step-by-step explanation:

Given

\frac{3}{4} (- 12x + 4) + \frac{1}{2} (6x + 8) ← distribute parenthesis

= - 9x + 3 + 3x + 4 ← collect like terms

= - 6x + 7 → A

If x is divided by 2 and then 4 is subtracted, then the function is f left parenthesis x right parenthesis equals x divided by 2
Anni [7]

The inverse is y = x/2 - 4

Steps involved are -

  1. replace f(x) with y:   y = 2(x + 4)
  2. Then switch y and x:   x = 2(y + 4)
  3. Finally make y the subject:
  4. x = 2(y + 4)
  5. x/2 = y + 4      (divide by 2)
  6. x/2 - 4 = y       (subtract 4)
  7. So, the inverse is y = x/2 - 4

<h3>What is the formula for inverse function?</h3>
  • In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
  • The inverse of f exists if and only if f is bijective.
  • f-1(y) = y/2 = x, is the inverse of f(x).
