Aj graphs the function plz

The answer to your question is below

Step-by-step explanation:

Part 1.- His mistake was that he drew the parabola upwards and it must be downwards.

Part 2.

             x                   Substitution                     f(x)

            -5                  -(-5+2)² - 1                         - 10

              1                  -(1 + 2)² - 1                         - 10

             2                  -(2 + 2)² - 1                          - 17  

The value of f(x) is always negative indicating that the parabola goes downwards.

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.

they can both be solutions depends on the equation
