The graphs of the function f(x) = cos(2x) and f-1(x)=cos-1(2x) intersect at x=a (a>0). Explain why a is a solution of the equation x-cos-1(2x)=0
If they "intersect", then what point is on both lines? How does this relate to "x = a", "y = cos(2a)", and "y-1 = cos-1(2a)"?The graphs of the function f(x) = cos(2x) and f-1(x)=cos-1(2x) intersect at x=a (a>0). Explain why a is a solution of the equation x-cos-1(2x)=0
