1. F (x)=2 x +6 Evaluate f (2) 2. F (x)=3 x Evaluate f (a +1) 3. F (x)=3 x – 1 and g (x)=5 x +3 Evaluate f (2)+ g (3)

1) f (x)=2 x +6 f (2)=2 (2)+6=4+6=102) f (x)=3 x f (a +1)=3 (a +1)=3 a +33) f (x)=3 x-1 and g (x)=5 x +3 f (2)=3 (2) -1 f (2)=6-1=5 g (3)=5 x +3=5 (3)+32=15+3=18 f (2)+ f (3)=5+18=23.
