Expressed powers are those that aref(x) = 5x + 3; g(x) = 6x - 5 find f/g. (f/g)(x) = quantity six x minus five divided by five x plus three. domain {x|x ≠ five over six. } (f/g)(x) = quantity five x plus three divided by six x minus five. domain {x|x ≠ three over five } (f/g)(x) = quantity five x plus three divided by six x minus five. domain {x|x ≠ five over six. } (f/g)(x) = quantity six x minus five divided by five x plus three. domain {x|x ≠ - three over five. }
