Answer:

  578/5

Step-by-step explanation:

You want the value of f(8) when f(x) = (9x² -2x +18)/(x -3).

Evaluation

To find f(8), put 8 where x is and do the arithmetic.

  [tex]f(x)=\dfrac{(9x-2)x+18}{x-3}\\\\\\f(8) = \dfrac{(9\cdot8 -2)8 +18}{8-3}=\dfrac{70\cdot8+18}{5}=\boxed{\dfrac{578}{5}}[/tex]
