The function f f\,f is defined by
f(x)=2arcsin(x−1)f(x) = 2\arcsin(x - 1)f(x)=2arcsin(x−1)
where f f\,f has its greatest possible domain.
Using set notation, state the domain of fff.
Using set notation, state the range of fff.
Find the exact value of f(1.5)f(1.5)f(1.5).
State the coordinates of the endpoint of the graph of y=f(x)y = f(x)y=f(x) at which both x x\,x and f(x)f(x)f(x) take their greatest values.
