Composition and Inverse Mat222 2/23/2013 This week we have been assigned three functions which we must evaluate. These are the functions which we have to evaluate this week. fx=2x+3 gx=x2-3 hx=7-x3 We have been asked to compute(f-h)(4). So we can evaluate each separately and then subtract. f-h4=f4-h(4) f4=24+3 =8+3=11 f4=11 h4=7-43 =33=1 h4=1 This is our final answer. f-h4=11-1=10 Next we are to compare two pairs of the functions
