Question

What is the possible discriminant of the graph?

–17

0

12

49

Answer 1

@Zekarias its (-6,0)

Answer 2

\[f(x)=(x+6)^{2}=x^{2}+12x+36\]\[b^{2}-4ac = 12^{2}-4\times 36= 0\]

Answer 3

Here is the basic point
If the graph of a quadratic function touches the x axis at one point, then the discriminant is ZERO.
