Please I need help and it has two answers for each one

1st Q: 3rd option, 2nd Q: 2nd, 4th, and 5th options

Step-by-step explanation:

For the first one, since the coefficient of the 2nd degree term is negative, the graph of the parabola will look downward, f(x) getting closer to infinity as the absoloute value of x gets larger.

For the second one, let f(x)=0 and solve the quadratic function with factoring. The equation can be rewritten as (x-12)(x+6)=0, so the roots are 12 and -6, which are x-intercepts. The y-intercept is the constant term of quadratic functions, so -36 is the y-intercept.

Solution given:

for second

we have

f(x)=x²-9x-36

let

y=x²-9x-36

when

x=0

y=-36

when

y=0

0=x²-9x-36

x²-12x+3x-36=0

x(x-12)+3(x-12)=0

(x-12)(x+3)=0

either

x=12

x=-3

So,

x and y intercepts are (-3,0)(12,0) and 0,-36)

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.
