Find and simplify each of the following for

f%28x%29=3x%5E2-9x%2B8
A.

+f%28x%2Bh%29=3%28x%2Bh%29%5E2-9%28x%2Bh%29%2B8
+f%28x%2Bh%29=3%28h%5E2+%2B+2hx+%2B+x%5E2%29-9x-9h%2B8
+f%28x%2Bh%29=3h%5E2+%2B+6hx+%2B+3x%5E2-9x-9h%2B8
+f%28x%2Bh%29=+3x%5E2-9x%2B+6hx-9h%2B3h%5E2++%2B8

B
f%28x%2Bh%29-f%28x%29=3x%5E2-9x%2B+6hx-9h%2B3h%5E2++%2B8-%283x%5E2-9x%2B8%29
f%28x%2Bh%29-f%28x%29=3x%5E2-9x%2B+6hx-9h%2B3h%5E2++%2B8-3x%5E2%2B9x-8
f%28x%2Bh%29-f%28x%29=3h%5E2+%2B+6hx+-+9h
f%28x%2Bh%29-f%28x%29=h%283h+%2B+6x+-+9%29

C
%28f%28x%2Bh%29-f%28x%29%29%2Fh=h%283h+%2B+6x+-+9%29%2Fh
%28f%28x%2Bh%29-f%28x%29%29%2Fh=3h+%2B+6x+-+9
