Answer:

so the answer is A (1) the roots are same...

Step-by-step explanation:

Sry dude....i dont where did my formula go ..

but here at the place of x axis , y= 0..

it means the function= 0 but there is only one point...then it's roots are equal...and extra info....the function is always positive or 0 only... and here when it has same roots ...in form of ax^2 + bx + c=0

b^2 = 4ac...
