Question

Which function rule is represented by the table?

Answer 1

Hint: Determine whether or not this is a linear (straight line) function.
Treat (0,3) and (2,7) as p oints.
Find the slope of the line connecting these two points. Then try to find the y-intercept of the line.

Answer 2

Ermm, I don't really understand what you mean

Answer 3

First, please explain in your own words what this problem is asking you to do.

Answer 4

To find what rule (such as add three, divide by two) the table is using?

Answer 5

If you believe that "add three, div. by 2" is the rule / relationship, write it out and try it.
Does it correctly predict other values in the given table?

y=(x+3)/2

I'm not saying this is correct; instead, I tried to write symbolically what you told me.

Answer 6

Well the top is add one (I think) because 0+1=1 1+1=2 2+1=3 and the X part of the table is 0,1,2,3.

Answer 7

And the bottom seems to be adding three.. so add 1 than add 3?

Answer 8

Have you actually checked each solution? If you choose one of the x values in the table and substitute it into the equation, the equation MUST correctly predict y.

Do a few examples, and show all of your work and your conclusions, please.

Answer 9

Honestly im so confused right now. Thanks so, so much for the help but im going to go to a live lesson (doing Eschool) and see if that helps, because sometimes its easier to have a person verbally speaking . Thanks again anyways though.

Answer 10

You're welcome. Keep in mind that the goal of this problem is to come up with a linear relationship between x and y; its form might be as simple as y=mx+b.
