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).

Luden [163]

Answer:

£270

Step-by-step explanation:

Works 7.5 hours per shift and there are 5 shifts in a week, hence

hours worked per week = 7.5 × 5 = 37.5

Pay per hour = £7.20, thus

Earnings for a week = 37.5 × 7.20 = £270
