Exer. 21–34: Find (a) (fºg)(x) and the domain of fºg and (b) (gºf)(x) and the domain of g f. 21 f(x) = x² – 3x, 8(x) = Vx+2 3 38

24 f(x) = -x + 1, 8(x) = VE – 5 25 f(x) = Vx – 2, 8(x) = Vx+5 – 3 26 f(x) = V3T g(x) = x + 2 27 f(x) = V3 – x. g(x) = VX? – 16 28 f(x) = x + 5, 8(x) = VX-5 29 f(x) 2x + 3 5 8(x) 5x – 3 2 30 f(x) = – g(x) = x-1 + 4 31 f(x) = x? 862) = – 3 3 32 f(x) = -2 8(x) 2 – 1 33 f(x) g(x) =* =* – 2 3-x + 2
