inverse of f(b)=(b+6)(b-2)

inverse

f (b) = (b + 6) (b - 2)

- 2 + b + 16, - b + 16 - 2

Solution steps

y = (b + 6) (b - 2)

Replace

b

with

y

b = (y + 6) (y - 2)

Solve for

y, b = (y + 6) (y - 2)

- 2 + b + 16, - b + 16 - 2

f (x) = \frac{8}{x - 3}

lo g_{3} (9)

f (x) = - \frac{1}{4} x

f (x) = x^{2} - 7 x + 12

f (z) = \frac{4 z ^{2}}{( z - 3 ) ( 3 z + 1 )}
