For the function f(x) = -2(x + 3)2 -1, identify the vertex, domain, and range. (2 points) a. The vertex is (3, -1), the domain is all real numbers, and the range is y ≥ -1.
b. The vertex is (3, -1), the domain is all real numbers, and the range is y ≤ -1.
c. The vertex is (-3, -1), the domain is all real numbers, and the range is y ≤ -1.
d. The vertex is (-3, -1), the domain is all real numbers, and the range is y ≥ -1.
I NEED HELP ASAP!

the answer is b

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
