For f%28x%29+=+2-3x and g%28x%29=+3x+-2 , find the indicated values.
1.)
f%28a+%2B+b%29
f%28x%29+=+2-3x ..........if x=a%2Bb, we have
f%28a+%2B+b%29+=+2-3%28a+%2B+b%29+
f%28a+%2B+b%29+=+2-3a+-+3b

2.)
g%28a%29+-g%28a-b%29+%2B+f%28a%29

if g%28x%29=+3x+-2 and x=a, we have
g%28a%29=+3a+-2

g%28a-b%29+=3%28a-b%29+-2=+3a-3b-2

f%28a%29=+2-3a
than we have:
