Question

NEED HELP!! Quadratic Equations and functions question.

Answer 1

Answer:

B and D are correct

Step-by-step explanation:

Hello,

to find the zeroes we need to solve y = 0

so D is correct

and we can write

$-5(x-4)^2+10=0\\<=>5(x-4)^2=10\\<=> (x-4)^2=10/5=2\\<=> x-4=\sqrt{2} \ or \ x-4=-\sqrt{2}\\<=> x=4+\sqrt{2} \ \ or \ \ x=4-\sqrt{2}$

so B is correct

hope this helps

Answer 2

B and D are the correct answers, I just took the test! <3
