Question

Identify the graph of a quadratic equation with no real solution

Answer 1

If there is NO real solution, then the graph can NEVER touch the x-axis.

Answer 2

Because where it DOES touch the x-axis, is where there will be a real solution or solutions.

Answer 3

Oh

Answer 4

You can now pick the correct choice. No need to list them.

Answer 5

Good Afternoon.

Answer 6

Loll Good afternoon as well

Answer 7

Okay I'm still confused but i dont think either of them is a real solution

Answer 8

The 3 graphs you showed, all touched the x-axis in at least one place. So those quadratics can have real solution(s).

Answer 9

Thats what i'm thinking I think that the last one i didnt show is not a real solution

Answer 10

If you graph, for example, y = x^2 + 1, the graph never touches the x-axis. Therefore, if you solve x^2 + 1 = 0, there will be no real solutions.

Answer 11

Oh ok one second because isnt the third one touching the x

Answer 12

See...I showed you x^2 + 1...it never touches the x-axis.

Answer 13

Yes, the 3rd one touches...so it will have a real solution.

Answer 14

Your original question..which will NOT have a real solution?

Answer 15

Makes sense?

Answer 16

Yes but could i show you the fourth graph because it looks like that one is touching too

Answer 17

Sure.. Show the 4th graph.

Answer 18

The 4th graph NEVER touches the x-axis!

Answer 19

It can touch the y-axis. We are only concerned about touching the X-AXIS!

Answer 20

Oh it doesn't? I thought it did sorry I am the worst at graphing

Answer 21

The x-axis is the horizontal line.

Answer 22

Oh i see

Answer 23

so the correct choice is the 4th graph.

Answer 24

Ok ty
