Select the counterexample to this conjecture:
a pair of supplementary angles includes one obtuse angle.
a.90º + 90º = 180º b.120º + 60º = 180º c.100º + 80º = 180º d.110º + 70º = 180º

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
