1) The linear function f(x) is continuous and monotonous in all the range.
2) The rational function g(x) may or not be monotonous and continue in the range (3,4)
3) The lack of information about continuity of the function g(x) does not permit to conclude whether f(x) = g(x) in the range (3,4).
Because two fractions are equal fractions when they represent the same part of a whole. if denominators are different you need to first equal the denominator then further proceed to solve
