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
