If I were looking at a graph of a quadratic equation, how do I determine where the solutions are?

Answer 1

if it is a function like

ax^2 + bx + c = y

then the solutions are when y=0, i.e. where the line crosses the x axis.

Answer 2

Thank you! Is this case for all functions?

Answer 3

If b^2<4ac the solutions are imaginary.

if b^2=4ac there is only one solution
where
x=-b/2a

Answer 4

Okay I think I understand now. Thank you!
