Answer:
The following numbers ARE functions:
2, 3, 6, 7, 9, 12
Step-by-step explanation:
A function is only possible if the x values have NO REPEATING NUMBER!!!
Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.
<u>Question 1</u> has the 8 and 4 with 2 numbers.
<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)
<u>Question 5</u> has numbers 1 and 5 repeating many times
<u>Question 8</u> numbers 1 and 2 are repeated twice
<u>Question 10</u> number 3 repeats twice
<u>Question 11</u> has the 1 repeated
I hope my answer can help you.
The graph of the given quadratic equation will be along the y-axis and cuts the intercepts at x (-1,3) points.
<h3>What is a graph? </h3>
A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given quadratic equation is:-
y = x² - 2x - 3
So the value of x will be (-1,3) so the quadratic curve will cut the intercepts at x(-1,3). The graph of the quadratic equation is attached with an answer.
