Question

5 algebra 2 questions...

Answer 1

Sec, I got you

Answer 2

By sec you mean one moment or the second one?

Answer 3

One moment. As you can see, upon graphing the points, it opens upward thus we can exclude Option B as the -x^2 indicates that it opens downward.

Answer 4

So it's not B?

Answer 5

Oh wait for this question you try to find out which one of the answers have the same points in the chart?

Answer 6

So I was going to try do it one way but it turns out it's rather boring. But yes, technically. One of those lines to the left graphs the points on the right.

Answer 7

Okay let me try and see if I get it right

Answer 8

One easy way to approach this is by determining the vertex of the graph. We can see that -3 is the lowest y value, so we know that (2,-3) is the vertex. You can graph the other ones using Desmos and the like and see which one matches up with that.

Answer 9

Would it be D.?

Answer 10

Yep.

Answer 11

Okay :)

Answer 12

I went ahead and tried to do this while waiting and I'm stumped....

Answer 13

holy taco Hanna

Answer 14

Actually this is the same exact thing ._.

Answer 15

Which one can we eliminate from the get go?

Answer 16

C.?

Answer 17

Wait...

Answer 18

D.?

Answer 19

It can't be D. because it would be upside down.

Answer 20

mhm

Answer 21

If I type that equation into Desmos and don't put ^ above the y will it mess my equation up?

Answer 22

No. Although what you ought to do is input the set of coordinates: equation(1, 5.9), (2,8.9), (3,13.4), (4, 20.1), (5, 30.1), (6, 45.7), (7, 67.7)

If you give those to http://www.wolframalpha.com it will give you the line of best fit.

Answer 23

So do I go to Desmos and type all he equitation in until I get the same answer?

Answer 24

Uh no, you type "equation(1, 5.9), (2,8.9), (3,13.4), (4, 20.1), (5, 30.1), (6, 45.7), (7, 67.7)" into the website I gave you.

Answer 25

Oh okay

Answer 26

So would the answer be C.?

Answer 27

Looks like it.

Answer 28

I'm highly confident you can use Wolfram/Desmos for the rest of these.

Answer 29

Okay thank you so much!!

Answer 30

No problem
