Brut [27]

Answer:

$b(a) =\frac{a}{7} -5$

Step-by-step explanation:

Given

$A(b) = 14 * \frac{b + 5}{2}$

Required

Determine the inverse function b(a)

Write A(b) as a

$a = 14 * \frac{b + 5}{2}$

Swap a and b

$b = 14 * \frac{a + 5}{2}$

$b = 7(a + 5)$

Divide both sides by 7

$a + 5 = \frac{b}{7}$

Maka a the subject

$a =\frac{b}{7} -5$

Swap a and b again

$b =\frac{a}{7} -5$

Hence:

$b(a) =\frac{a}{7} -5$
