Question

I need help with this algebra 2 question PLEASEEE

Answer 1

What is the possible discriminant of the graph?

a parabola opening up x intercepts near negative 7 and negative 3

–13

0

15

16

Answer 2

Discriminant is when y = 0 right? I don't really know.

Answer 3

"Near" is kind of an odd instruction. But if we play like it is EXACTLY -7 and -3, we might get

(x+7)(x+3) = x^2 + 10x + 21 and the discriminant is 100 - 4(1)(21) = 16

Tricky little problem. I've actually never seen one like it. I like this one. It requires some thought and imagination.

Answer 4

That's the discriminant? I see.

Answer 5

ohh okay thank you
