Which of the following relations is a function?
OA. {(3,-1), (2, 3), (3, 4), (1,7)} OB. {(1, 2), (1,3), (2,8), (3,9)} O c. {(3, 0), (4,-3), (6, 7), (4,4)} OD {(1, 2), (2, 3), (3, 4), (4, 5)}
The definition of a function is that every input, x, must have only one output, y. So, for every x value, there should be only one y value with it. If you have two x values that are the same and have different y values, then that is not a function. The only answer that showcases this is letter D.
1 → 2
2 → 3
3 → 4
4 → 5
In this function, every input has one output and each x value is different.
Answer from: Quest
no association
step-by-step explanation:
if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
Answer from: Quest
see attached
step-by-step explanation:
given the function as;
write the equation replacing f(x) with y
form and fill a table containing values of y with corresponding values of x
you can take a range for values of x as -3≤x≤3
solving for x=-3
for x=-2
repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3
plot the values of y against values of x and obtain the following graph

What two criteria are needed for triangles to be similar
Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.
