Answer for correct brainliest The function f(x) = –x2 – 4x + 5 is shown on the graph.

On a coordinate plane, a parabola opens down. It goes through (negative 5, 0), has a vertex at (negative 2, 9), and goes through (1, 0).
Which statement about the function is true?

1.The domain of the function is all real numbers less than or equal to −2.
2.The domain of the function is all real numbers less than or equal to 9.
3.The range of the function is all real numbers less than or equal to −2.
4.The range of the function is all real numbers less than or equal to 9.

the answer is b i just did that

answer: your gay

step-by-step explanation:

you dont know math

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
