11.2.3 Quiz: Completing the Square

Mathematics
1 answer:
Allushta [10]3 years ago
3 0

Answer:

A. The zeros is at: 3 \±\sqrt 2

B. The zeros are the hot dog prices that give $0.00 profit (no profit)

Step-by-step explanation:

Given

y = -2(x - 3)^2 + 4

Solving (a): The zeros of the function

To do this, we equate y to 0.

y = 0

So, we have:

-2(x - 3)^2 + 4 =0

Subtract 4 from both sides

-2(x - 3)^2 + 4 -4=0 -4

-2(x - 3)^2 = -4

Divide both sides by -2

(x - 3)^2 = 2

Take the square root of both sides

(x - 3) = \sqrt 2

Add 3 to both sides

x  =3 \±\sqrt 2

<em>Option (b) interprets the zeros</em>
