Answer 2

wel.ll.. pretty much the same way

Answer 3

\(\bf f({\color{brown}{ x}})=\cfrac{24}{3{\color{brown}{ x}}-2}\qquad \qquad f({\color{brown}{ -2}})=\cfrac{24}{3{\color{brown}{ (-2)}}-2}\)

Answer 4

notice, all you do is replace any "x"s in the equation by the "given" value

Answer 5

-6?

Answer 6

\(\bf f({\color{brown}{ x}})=\cfrac{24}{3{\color{brown}{ x}}-2}\qquad \qquad f({\color{brown}{ -2}})=\cfrac{24}{3{\color{brown}{ (-2)}}-2}\to \cfrac{24}{-6-2}\to \cfrac{\cancel{ 24 }}{-\cancel{ 8 }}\)
