C) f(x) = cosec"X-cor x and g(x)-Let f(x) be a function whose domain is(A) [一4, 1]5,7] Let g(x)-2x + 51 then domain of (fog) (x) isB-2(D) I-5,7] |

Answer» g(x) = |2x+5| its domain is R Now for f(x) given domain is [-5,7]So for domain of f(g(x)) take the intersection of R and [-5,7] .so we get the that is [-5,7]. so option D) is correct |
