Warm-Up Use long division to change (2x+1) / (x-1) to a mixed fraction. 2x+1/x-1= 2+(3/x-1) 2. If f(x)=3x+2, what is f(2-x)? f(x)=3x+2 3(2-x)+2 6-3x+2 f(2-x)=8-3x 3. a) Show how y=f(x+4) differs from f horizontal: shift left by 4 units b) Show how y=3g(2-x)-5 differs from g horizontal: flip over y-axis...
