Suppose that ()=ℎ−1() j ( x ) = h − 1 ( x ) and that both j and ℎ h are defined for all values of x . Let ℎ(8)=4 h ( 8 ) = 4 and (9)=−1 j ( 9 ) = − 1 . Evaluate if possible and enter the value of the expression in the blank. If you do not have enough given information to evaluate the expression, enter unknown in the blank beside the expression.
