@satellite73 can you help me with this problem?

anonymous · Answer

@ganeshie8 can you help me?

ganeshie8 · Answer

look at the graph, there will not be any real solutions since the graph is NOT touching the x axis

ganeshie8 · Answer

that means there will be complex solutions

ganeshie8 · Answer

that happens precicely when the discriminant is `negative`

ganeshie8 · Answer

look at the given options,
which option has negative determinant ?

anonymous · Answer

-16?

anonymous · Answer

so complex solutions are typically negative numbers?

ganeshie8 · Answer

thats right ! a negative determinant results in a complex solutions for the graph

anonymous · Answer

Okay I get it better now!! thank you so much

ganeshie8 · Answer

geometrically it represents a parabola which stays completely above the x axis. or completely below the x axis

anonymous · Answer

oh okay, thanks again!
