Answer:

f(-2)=-3

Explanation:

The function given to us is:

f(x)=(24)/(3x-2)

We want to find
f(-2) .

We just have to substitute
x=-2 into the given function to obtain;

f(-2)=(24)/(3(-2)-2)

We multiply out in the denomerator to obtain;

f(-2)=(24)/(-6-2)

We simplify in the denominator to obtain;

f(-2)=(24)/(-8)

$\Rightarrow f(-2)=(3* 8)/(-8)$

Cancel the common factors to obtain;

$\Rightarrow f(-2)=-3$
