In this table, the input and output values are related. If you know the input, you can predict the output. Which rule describes how the output depends on x?

Solution

the correct equation is -x²+13

x=0 then -(0)²+13=13

x=1 then -(1)²+13=12

when x=2 then -(2)²+13=9

x=3 then -(3)²+13=4 , the correct answer is -x²+13
