Step-by-step explanation:

The given options are,

a) f(x) = 2^{(3x)}

b) f(x) = ({\frac {1}{2}})^{3x}

c) f(x) = 2 \times ({\frac {1}{3}})^{x}

natka813 [3]

Step-by-step explanation:

The given inequality is :

-27\ge \dfrac{1}{2}(6x-12)

Solving RHS of the inequality:

-27\ge \dfrac{1}{2}\times 2(3x-6)\\\\-27\ge (3x-6)

Adding 6 both sides of the inequality

-27+6\ge (3x-6)+6\\\\-21\ge 3x\\\\x\le -7

The attached figure shows the graph for the given inequality.
