Expert Answer:

open vertical bar x minus 1 close vertical bar to the power of A equals open parentheses x minus 1 close parentheses to the power of 7 A equals log subscript 3 X squared minus 2 log subscript 3 9 space A equals 7 equals log subscript 3 X squared minus 4 space w h e n space X greater than 1 11 equals log subscript 3 X squared X equals 3 to the power of 11 over 2 end exponent
