Question

What is the possible discriminant of the graph?


... hold up ima show u the graph

Answer 1

i have no idea how to figure this out ;(

Answer 2

From what I can tell, the x-intercepts/solutions/zeroes, are irrational.
The discriminant is b^2 - 4ac.
If it is a perfect square, the two roots will be rational and it can be factored.
If it is negative, the roots will be complex and therefore never intersect the x-axis.
If it is 0, then it means that there will be a double root.
If it is any positive number that is not a perfect square, then the roots are irrational.
Based on the fact that the roots are irrational, what are the possible values fro the discriminant?

Answer 3

uhhh... 0??

Answer 4

no no no no isnt it -11 @Calcmathlete

Answer 5

Again, If it is any positive number that is not a perfect square, then the roots are irrational.

Answer 6

so is it 25?

Answer 7

You've said every choice except the correct one.

Answer 8

25 is a perfect square meaning it would be rational roots.
0 would mean it is a double root.
-11 would mean it's an imaginary root.

Answer 9

Do you get it?

Answer 10

so its 73 right?

Answer 11

Yes.
