Graph - x + 2y = - 2 for Domain {-4, - 2, 0, 2, 4}.

i) 15 x2 y - 20 xy2 ... (ii) Similarly, g^-1 (x) = 2x (since x = y/2 and hence y = 2x) ... that the interval of the domain (first coordinate) for which F (x) < 0 is just: - 3 < x < 2 ... 4) The graph for the quadratic is sketched as the parabola in the uppermost graphic ... We dispense with the negative root as unphysical, leaving c = 5 m
