Answer 1

You put it in the English section. lol

Answer 2

What do you think is the answer?

Answer 3

Moved to Mathematics.

Answer 4

Ah, thanks Tranq

Answer 5

The x-value represents length, so which two options can you rule out?

Answer 6

Mhm, the vertex will give you the highest y-value for a parabola...the y-value is area, so based on that, what do you think is the answer?

Answer 7

Yep, you got it.

Answer 8

Yep, I'd agree with that. It starts falling after 0.5s, because that's when it stops going up. And it falls the rest of the way.

Answer 9

No, that's not right. The y-intercept is what 'y' is when 'x' is equal to 0. What does 'x' represent here?

Answer 10

What is 'x' and what is 'y'? Look at the table.

Answer 11

Yes...the table says "Years since 1975", and what is 'y'?

Answer 12

Yes, y-intercept is what 'y' is when 'x' is 0. Or in this scenario, the y-intercept is what the population is when the years since 1975 is 0.

Answer 13

So what do you think is the answer?

Answer 14

"years since 1975 is 0", that means the year is 1975.

Answer 15

Yes, that's correct.

Answer 16

Okay, what does 'x' represent in this scenario?

Answer 17

Yes, and the vertex of a parabola represents either the minimum y-value or the maximum y-value, depending on which direction it opens up. What is it here?

Answer 18

Yep, so based on this information what do you think is the answer?

Answer 19

No, the minimum height is at the vertex. The x-coordinate represents the horizontal distance from the left side.

Answer 20

No, C represents the y-coordinate, we are looking for what the x-coordinate represents.

Answer 21

Yes, that would be correct.
