Answer :
Hi so im not so sure if this is right bc i dont know what y is but im pretty sure a= -2. i got this by plugging in x. so 8*4= 32... y=ax2 + 32 -3. then y=a8 + 32 - 3 next y= a8 + 29. so i tried -2 and it gave me a positive 13 and then i tried -11 and it gave me -59. And to be honest i believe it will be a positive answer so ima go with -2.
Answer: its -1
Step-by-step explanation: the other person is incorrect and i already tried 1 and got it wrong
