When -2 is substituted for x, in the equation y=x2+1 what is y.

5

Step-by-step explanation:

1) so lets substitute -2 as x:

y=(-2)^2+1

(-2)^2=-2*-2=4

hence

y=4+1

y=5

Hope this helps

y = -3

Step-by-step explanation:

plug in the x value,  y = -2(2) + 1

simplify, y = -4 + 1

simply again,  y = -3

we can plug the y and x in to make sure it is equal

-3 =  -2(2) + 1

simplify, -3 = -4 + 1

simplify again, -3 = -3

add 3 to both sides, 0 = 0

one possible answer is -3 for y, and -2 for x
