7) if f(x) 22 and h(x) = x - 1, then which of the following options is(are) incorrect? foh is not an injective function. foh is an injective function f(f(h(x))) > h(x) = (x - 1)4 f(f(h(x)) > h(x) = (x - 1)5 8) if f(x) = r°, then which of the following options is the set of points where the graphs of the functions f(x) and f-1(2) intersect each other? {(-1,1),(0,0), (1, -1)} {(-2,-8),(1, 1), (2,8)} {(-1,-1),(0,0), (1, 1)} {(-2,-8), (0,0), (2,8)}
