[" If "a>0" and "b^(2)-4ac=0" ,then the curve "y],[=ax^(2)+bx+c]

if a gt 0 and b^2 - 4ac =0 , then the curve y= ax^2 +bx +c

If a>0 and b^(2)-4ac<0, then the graph of y=ax^(2)+bx+c

If a>0 and b^(2)-4ac=0, then the graph of y=ax^(2)+bx+c touches x -axis and lies above x -axis.

If a,b,cd in R and I is a root of the oquation ax^(2)+bx+c=0, then the curve y=4ax^(2)+3bx+2ca!=0, intersects x -axis at

If a=c=4b , then the roots of ax ^(2) + 4 bx + c =0 are

If f(x) = a + bx + cx^(2) where c > 0 and b^(2) - 4ac < 0 . Then the area enclosed by the coordinate axes,the line x = 2 and the curve y = f(x) is given by

If f(x) = a + bx + cx^(2) where c > 0 and b^(2) - 4ac < 0 . Then the area enclosed by the coordinate axes,the line x = 2 and the curve y = f(x) is given by

If a,b,c are rational,if b^(2)-4ac=0 then nature of the roots of the equation ax^(2)+bx+c=0(a!=0) are
