Prove the true ones and give a counter example for the false ones a) If f and I are continuous on 19.6], frane glas and f(b) > g(6), then there is a cca.bI such that fcc) – grey b) suppose that fandy are defined and finile Volved an open inken val I which contains a, that fis cóntinuous at a, and that fla) & 0. Then g is if and only it tog is continuous ata c) Suppose that f and g are defined and finik veleed on R. Iff and gof are continuous on R, then gis continuous on R d) The function is uniformly.combinuous mx+b on (0,1) for all on is continuous at a کا صهک CASK m, GER
