Consider f(x)= 2x+1 and g(x)=3x-5.
Find (f-g)(x)
What is -x+6?
(f-g)(x)
=f(x)-g(x)
=(2x+1)-(3x-5)
=2x+1-3x+5
=-x+6

Let g(x)= -x2+2x+3 and h(x)= x2-x+2
Find (g/h)(1)
What is 2?
(g/h)(1)
=g(1)/h(1)
=[-(1)2+2(1)+3]/[(1)2-(1)+2]

Let f(x)=2x2+1 and g(x)=x-1
Find (fog)(x)
What is 2x2-4x+3?
(fog)(x) = f(g(x))
= f(x-1)
= 2(x-1)2+1
= 2(x2-2x+1)+1
= 2x2-4x+2+1
= 2x2-4x+3
