What is the value of g^-1(9)
mars1129 [50]
Hi there!

• g(x) = 6x - 3

Then,
if g(x) = y :-

y = 6x - 3

⇒6x = y + 3

⇒x = \dfrac{\text{y} + 3}{6}

According to th' question :-

g⁻¹(x) = \dfrac{\text{x} + 3}{6}

g⁻¹(9) = \dfrac{9 + 3}{6}

g⁻¹(9) = \dfrac{12}{6}

g⁻¹(9) = 2

Hence,
The required answer is g⁻¹(9) = 2

~ Hope it helps!
