Graph the data set { ( 1 , − 2 ) , ( 3 , − 6 ) , ( − 3 , 6 ) , ( − 5 , 10 ) , ( 9 , − 18 ) } { ( 1 , - 2 ) , ( 3 , - 6 ) , ( - 3 , 6 ) , ( - 5 , 10 ) , ( 9 , - 18 ) }

B? ? i'm most likely wrong but i think it would be b

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
