Question

NEED HELP!! Quadratic Equations and functions question.

Answer 1

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

Answer 2

B and D are correct

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=√(2) \ or \ x-4=-√(2)\\<=> x=4+√(2) \ \ or \ \ x=4-√(2)`

so B is correct

hope this helps
