Respuesta :

is B (x=2) because y=5x^2 then x=2 then 2^2 because x^2 and it comes out 4.then 5x4=20 then 10 is wrong because it's right 20
Substitute the x value for the x in the function. In B when you put two in you should get

2^2= 4
4 x 5=20

So y should be 20, but in the table y is 10

Therefore, B is wrong

* do the same thing for all the options to double check
