(Chapter 1: Review) 1.24 We then need fto apply the square root operation. We will let fu()=u. The use of uis more helpful in Calculus, but fx=xis also acceptable. However, =xis not acceptable. Possible Answer: =uand gx=u±=3x+1. We can check this to see that fgx=x+1. Note: Here’s the complete input-output model: x±g:=3x+1±u=3x+1±f:=uf±g²³´´´´´´´´µ´´´´´´´´±=3x+1Note: There are infinitely many other possibilities. For example, we
