Answer a because if you replace the x with -1,0, and 3, you will get 5,1,and 37.
The mapping for the function y = 2 x + 1 with the replacement set { − 1 , 0 , 3 } consists of the ordered pairs ( − 1 , − 1 ) , ( 0 , 1 ) , ( 3 , 7 ) . This was determined by plugging in each value of x into the function to find the corresponding y values.
