part i) To find f inverse, convert f(X) to x and x to y so, x = (root of y + 3 / 2 ) + 1 = ( x - 1 ) => (root of y + 3 / 2 ) = 2(( x - 1 )^2) -3 => y Now convert y = f inverse. when you open the bracket you get is 2x^2 - 4x - 1 part ii) (NOTE >= means greater or equal to) Range of F(X) is...- Thought blocker

(1-(sin^2x/cos^2x)) --------------------------- = (1+(sin^2x/cos^2x)) (cos^2x-sin^2x) -------------------------- (cos^2x+sin^2x) Now, Using the identity , if we subtract from both sides, we obtain so, 1-2sin^2x / 1 = 1-2sin^2x ;)- Thought blocker
